Fenugreek

Trigonella foenum-graecum L. · also called Fenugreek, Greek hay, alholva or fenogreco (Spanish), fenugrec (French), Bockshornklee (German), methi (Hindi), 胡芦巴 hú lú bā (Chinese)

Fenugreek is a legume plant whose seeds are a common spice in curries and are also sold as ground seed, seed extracts, fibre and milk-boosting teas. It is in the same plant family as peanut and soya. Cooking with it is normal; this profile is about fenugreek taken as a health product. The best-studied use is blood sugar in people with type 2 diabetes, rated low. Cholesterol, after-meal sugar, menstrual pain and menopause symptoms are also low. Testosterone, milk supply, blood pressure and several other uses are very low, and body weight is against. Fenugreek can lower blood sugar, can cause serious allergy in people with peanut or other legume allergy, is not recommended in pregnancy, and can make urine and sweat smell of maple syrup.

About Fenugreek

Fenugreek (Trigonella foenum-graecum) is a legume whose seeds are a familiar curry spice. The seeds are also sold as ground seed, seed extracts, fibre and milk-boosting teas. Its best-studied use is blood sugar in people with type 2 diabetes, rated low: several pooled analyses of small, mostly low-quality trials found modest falls, one did not, and the US National Center for Complementary and Integrative Health says there is not enough high-quality evidence. Cholesterol, after-meal blood sugar from fenugreek foods, menstrual pain and menopause symptoms are also low. Testosterone in men and breast milk supply are very low, and body weight is against. Safety matters more than for most spices: maple-syrup body odour, blood sugar lowering with diabetes drugs, allergy including cross-reaction with peanut and other legumes, an effect on warfarin in one case, and a recommendation against use in pregnancy, breastfeeding and under age 18. For amounts, ask a doctor or pharmacist.

What it is

Fenugreek (Trigonella foenum-graecum) is an annual plant of the legume family (Fabaceae), related to peanut, soya, chickpea and lentil. The plant name is accepted in the GBIF plant database.

The seed is the part nearly always used. Studies in this profile tested ground seed, seed extracts (including patented, branded ones), seed fibre or flakes, fenugreek-enriched bread, and mixed teas and capsules. No human trial of fenugreek leaf was found. Because the products differ so much, a result for one product cannot be assumed for another.

Traditional and current uses

A review says fenugreek has been used in Iran, India and China for centuries, including for diabetes, milk supply and period discomfort. We could not check a dated source. The EU lists traditional use of fenugreek seed for temporary loss of appetite and, as a poultice, for minor skin inflammation, based on long-standing use only.

Today fenugreek is mainly taken for blood sugar and cholesterol, milk supply, male vitality and testosterone, and menopause symptoms. Most of these uses rest on small trials, many of branded extracts.

What the research shows

Blood sugar has the most research: pooled analyses of up to 14 small trials mostly found modest falls in fasting sugar and HbA1c, with big differences between trials and one analysis that did not find a fasting-sugar fall. Cholesterol and triglycerides fell slightly on average. Weight and BMI did not change.

For testosterone, the newest 2026 analysis found a small rise in total testosterone, no clear change in free testosterone and very low certainty. For milk supply, a Cochrane review found the evidence low to very low. Menstrual pain and menopause symptoms improved in a few small trials, mostly of branded extracts. Almost all studies were read as abstracts only.

Who needs to be careful

People with peanut, soya, chickpea or other legume allergy should avoid fenugreek; the EU lists this as a contraindication. People taking diabetes medicines or warfarin should tell their doctor first. The EU does not recommend fenugreek in pregnancy, in breastfeeding, in women who could become pregnant without contraception, or under age 18.

A mother who takes fenugreek, or a baby of a mother who took it during labour, may smell of maple syrup. That smell is harmless but can be mistaken for a rare newborn disease, so tell the medical team.

Tradition or eraDocumented useSource
Iran, India and China, traditional medicineA 2021 narrative review says fenugreek has been a notable multipurpose medicinal and traditional herb in Iran, India and China for centuries, with seeds and leaves traditionally used for digestion, milk supply, period and menopause discomfort, blood sugar and cholesterol. It cites no single dated source in the abstract; treat the dates as unverified.p33245271
Europe, EU traditional herbal medicineThe EU herbal monograph (first adopted 27 January 2011, revised in a March 2021 draft) lists two traditional-use indications for fenugreek seed: temporary loss of appetite (taken by mouth) and symptomatic treatment of minor skin inflammation (warm infusion applied as a cataplasm). The monograph says such use is based "exclusively on long-standing use" and not on clinical proof.s-ema-hmpc-fenugreek-draft
Milk supplyLactMed says fenugreek has been used in many regions as a galactogogue (a milk booster) and is in many proprietary milk-boosting mixtures.p30000838
Diabetes in AsiaThe first pooled analysis states fenugreek is widely used in cooking and as a traditional medicine for diabetes in Asia.p24438170
Modern science, from the 1990sAn early trial of defatted fenugreek seed in type 1 diabetes was published in 1990; the insulin-releasing amino acid 4-hydroxyisoleucine was isolated and described in 1998 (lab work). Wikipedia was not used for history.p2194788

Mechanisms, receptors and pathways

Target or pathwayGene or receptorWhat was foundLevel
Glucose-dependent insulin release from pancreatic beta cellsInsulin secretion (no single receptor identified in the abstracts)4-hydroxyisoleucine from fenugreek increased insulin release from isolated rat and human islets in a glucose-dependent way, and improved glucose tolerance in rats and dogs. This is lab and animal evidence; pooled human trials show only small changes in insulin resistance. 77 13 46Laboratory research
Slowed sugar absorption by seed fibreNot applicableAdded fenugreek seed flour lowered the glycemic index of baked foods in healthy adults, consistent with a fibre effect in the gut. No trial in the sources read measured the mechanism. 72 52 22Pharmacological theory
Insulin sensitivity and melanin-concentrating hormone (MCH)PMCH / MCHIn a clamp study in healthy volunteers the authors report improved insulin sensitivity that correlated with lower plasma MCH; abstract gives no numbers. 47Human data
Sex hormonesTestosterone, estradiol, FSH, SHBGTrials of branded extracts reported small rises in total testosterone in men (pooled SMD 0.25 to 0.32) and rises in estradiol or free testosterone in women in some trials. Mechanism unknown; the idea that saponins slow testosterone breakdown is from case-report authors, not tested here. 92 40 79 44 70Human data
Prolactin and milk productionPRLIn 68 mothers of preterm babies fenugreek did not change prolactin, while milk volume was higher on day 7 but not on day 15. LactMed says some studies suggest insulin, prolactin and oxytocin changes but that the effect may be mostly psychological. 73 1Human data
Drug-metabolising enzymesCYP2D6, CYP3A4Fenugreek extract blocked both enzymes in human liver microsomes at 50 to 100 microgram/ml, but in six volunteers taking the seed powder for a week, enzyme activity (urinary metabolite ratios) did not change significantly. 3Human data
Allergen cross-reaction with peanutIgE binding to 7S vicilin and 11S legumin storage proteinsFenugreek vicilin and legumin have homology to peanut allergens Ara h 1 and Ara h 3; IgE from peanut-allergic patients bound fenugreek proteins at 50 to 74 kDa. 24 23Laboratory research
Odour productionNot applicableSotolone is present in fenugreek and in the urine of patients with maple syrup urine disease; in sweat after fenugreek tea other compounds, notably 2,5-dimethylpyrazine, gave the best match to the odour. 68 56Human data

Absorption, metabolism and elimination

Absorption
No human blood-level data for diosgenin, protodioscin, trigonelline or 4-hydroxyisoleucine after eating fenugreek were found in the sources read.
Distribution
Not established in humans.
Metabolism
Not established in humans. Odour compounds appear in urine and sweat after fenugreek, showing that some constituents or their products are excreted that way.
Elimination
Not found. LactMed says the maple-syrup odour appears in urine, sweat, faeces and possibly breast milk.
Bioavailability
Not established. Extract makers claim better bioavailability for branded extracts, but no study read measured it in people.

Isolated compounds versus whole extracts

No single compound has been shown to explain fenugreek's effects in people. Trials used whole seed powder (grams a day), seed fibre, defatted flakes, food products and branded extracts standardised to saponins or protodioscin (hundreds of milligrams a day). Results for one preparation cannot be assumed for another, and several extract trials involve the product makers.

Nutritional composition

Fenugreek seeds are rich in protein, fibre and gum (a narrative review lists protein, fibre, gum, lipids, moisture, ash and starch), but a nutrient table was not retrieved. Spice amounts in cooking are very small compared with the trial amounts. The seed gum and fibre content explains why large amounts cause gut effects.

What is Fenugreek good for?

The main proposed uses and how strong the human evidence is for each. "Low" means small or inconsistent studies, "very low" means a single small or unclear study or reviewers who rate certainty very low, "mixed" means studies disagree, "against" means studies found no benefit, and "insufficient" means there is not enough to judge. Fenugreek in cooking is fine; these results come from specific seed products and extracts, and may not apply to cooking amounts or to other products.

Type 2 diabetes: blood sugar and HbA1cLow certaintyThis is the most studied use. Most pooled analyses of small trials found modest falls in fasting blood sugar and HbA1c in people with type 2 diabetes (for example fasting glucose about 1 mmol/l lower and HbA1c about 0.6 to 0.9 points lower). The trials are small, mostly low quality and disagree a lot, and one 2023 analysis found no clear fall in fasting or after-meal sugar. The US National Center for Complementary and Integrative Health says there is not enough high-quality evidence to say it helps diabetes. No trial measured diabetes complications. Prediabetes: slowing the move to diabetesVery low certaintyOne 3-year trial without a proper placebo reported fewer people moving on to diabetes, and a small 12-week extract trial lowered fasting and after-meal sugar but not HbA1c. A 6-month trial of a three-ingredient mix found no change. Too few and too different to say. Blood sugar after a meal: fenugreek added to foodLow certaintyIn three very small trials, fenugreek seed flour or flakes added to bread or meals lowered the rise in blood sugar after eating, in healthy people and in people with diabetes. These tested a few meals or 14 days, and one trial involved staff of the sponsor. Insulin resistance and insulin levelsMixed findingsTrials disagree. Some reported lower insulin and a better insulin-resistance score; a pooled analysis of 10 trials found no clear change in that score, and one small trial saw insulin rise. Cholesterol and blood fatsLow certaintyPooled trials found small average falls in total cholesterol (about 9 mg/dL), triglycerides and, in some analyses, LDL, and a small rise in HDL. The analyses disagree about LDL and triglycerides, the trials are small, and no trial looked at heart attacks or strokes. Blood pressureVery low certaintyTwo pooled analyses found the top number about 3.5 mmHg lower on average, and no clear change in the bottom number. This is a very small effect, far below that of a blood pressure pill. Weight loss (body weight and BMI)Evidence againstPooled trials found no change in body weight or BMI after fenugreek. Waist size was slightly smaller in one analysis. Fenugreek has not been shown to help weight loss. Fatty liver diseaseNot enough evidenceOne pilot trial of 30 people found no difference from placebo. Type 1 diabetesNot enough evidenceA short 1990 trial using a very large food-level amount of defatted seed reported lower blood sugar, but it is too small and old to judge. Fenugreek must never replace insulin. Testosterone levels in menVery low certaintyPooled analyses found a small average rise in total testosterone but no clear rise in free testosterone. The newest analysis (2026) rates the evidence very low in certainty, found no trial at low risk of bias, and says it does not support testosterone-boosting claims. Several trials were open-label or run by product makers. Male libido and sexual wellbeingLow certaintyTwo small placebo-controlled trials in healthy men reported better libido or "aging male symptom" scores. Both tested branded extracts, one in combination with minerals, and neither involved men with sexual problems. Women: sexual desire and arousalVery low certaintyOne 8-week trial of 80 healthy women with low sexual drive found higher desire and arousal scores than placebo, along with rises in estradiol and free testosterone. It has not been repeated. Muscle strength and exerciseVery low certaintySmall studies, mainly in young men who exercise, hint at slightly better strength and body fat, but in the pooled analysis the intervals for lean mass, fat mass and leg press included zero. Breast milk supplyVery low certaintyWidely used, but the evidence is very uncertain. A Cochrane review rated the evidence low to very low. Some small trials of fenugreek tea or capsules found more milk, one trial found a benefit only at day 7 and not day 15, and one trial of cookies found none. The National Library of Medicine database says the effect may be mostly psychological. See the safety tab before use. Painful periodsLow certaintySmall trials found less pain than placebo and about the same relief as a standard painkiller. A 2024 pooled analysis rates the evidence low quality and the effect "highly uncertain". Menopause symptoms (hot flushes, night sweats, mood)Low certaintyThree small placebo-controlled trials of three different branded extracts reported fewer hot flushes and night sweats and better mood scores. Two also saw rises in estradiol, which matters for women with hormone-sensitive conditions. None has been repeated by an independent team. Polycystic ovary syndrome (PCOS)Very low certaintyStudies of one patented extract reported smaller ovarian cysts and more regular periods, but two of the three studies had no placebo group and all come from the product developers. Appetite, fullness and fat intakeVery low certaintyThree tiny short trials suggest fenugreek fibre may make people feel fuller and an extract may slightly cut fat intake. Weight did not change. The EU lists use for temporary loss of appetite, so the effect on appetite is unclear. Prostate enlargement symptomsNot enough evidenceOne 12-week trial of 100 men found no improvement in prostate symptoms. Alzheimer's disease and Parkinson's diseaseNot enough evidenceTwo small trials, one in Alzheimer's disease (compared with the group's own starting point, not placebo) and one in Parkinson's disease, reported benefits. Both are preliminary and neither replaces medicine.

Type 2 diabetes: blood sugar and HbA1c

Low certainty

Pooled analyses of small trials usually find that fenugreek seed products lower fasting blood sugar and HbA1c a little in people with type 2 diabetes. But the trials are small, short, of mixed quality and disagree a lot, and one 2023 analysis found no clear fall in fasting sugar. The US National Center for Complementary and Integrative Health says there is not enough high-quality evidence to say whether fenugreek helps diabetes.

Studies, doses and limits

What the trials found

Eight pooled analyses of randomized trials were read. Neelakantan 2014 (10 trials) found fasting glucose 0.96 mmol/l lower, 2-hour glucose 2.19 mmol/l lower and HbA1c 0.85 points lower, but with large disagreement and mostly low-quality trials; the effect was seen only at medium or high doses in people with diabetes. Gong 2016 (10 articles) and Kim 2023 (10 trials, 706 people) also found falls in fasting glucose, 2-hour glucose and HbA1c. Khodamoradi 2020 (12 articles) found fasting sugar 12.9 mg/dL lower and HbA1c 0.58 points lower. Correia 2023 and Kumar 2023 (network analysis) were also positive. Against that, Shabil 2023 (14 trials, 894 people) found HbA1c fell by 0.88 points but fasting and after-meal glucose did not clearly change. Suksomboon 2011 found HbA1c 1.13 points lower in a few trials with a very wide range. Single trials include an 8-week trial of whole seed powder (10 g a day) in 88 people with diabetes that reported falls in fasting glucose and HbA1c versus a starch placebo, a small trial of 9 finishers that found no clear fall in fasting glucose at 2 g a day, and a sponsor-linked 204-person trial that reported larger falls than drugs alone but is unclear on blinding.

Results

Most pooled analyses report modest falls in fasting glucose and HbA1c in people with type 2 diabetes. The size varies a lot between trials and the quality is mostly low.

Effect sizes as reported

Neelakantan 2014: fasting glucose -0.96 mmol/l (95% CI -1.52 to -0.40; I2 80%), 2-hour glucose -2.19 mmol/l, HbA1c -0.85 (-1.49 to -0.22). Khodamoradi 2020: fasting sugar -12.94 mg/dL, HbA1c -0.58 (-0.99 to -0.17). Shabil 2023: HbA1c -0.88 (-1.49 to -0.27); fasting glucose not clear.

Why this rating

Pooled analyses agree in direction, but the trials are small and mostly low quality, the preparations and amounts differ, disagreement between trials is high (I2 70 to 87% for glucose), and one analysis did not find a clear fasting-glucose fall. The reviewers themselves ask for better trials.

Form and dose studied

Trials used whole seed powder (about 2 to 25 g a day in the trials read), seed extracts (about 0.5 to 1 g a day) and food products. Results from one preparation cannot be carried over to another.

Who was studied

Adults with type 2 diabetes, many already on diabetes drugs; most trials in South Asia, Iran and the Middle East.

Limits

Small and short trials; low quality in most; different products; publication bias is possible; blood sugar numbers are not the same as fewer complications, which no trial measured.

Why researchers looked

Fenugreek seed is a traditional food and medicine for diabetes in South Asia, so many trials have tested it.

Traditional use

Used in South Asian and Middle Eastern cooking and traditional medicine, including for diabetes (Neelakantan 2014 abstract).

Proposed mechanism Laboratory research

Lab work shows an amino acid from the seed, 4-hydroxyisoleucine, makes isolated pancreatic islets from rats and humans release more insulin, but only when sugar is already high. The seed also holds a lot of gum fibre that may slow sugar uptake in the gut. These are lab and animal findings, not proven in people.

A proposed mechanism does not show that the effect happens in people.

Fenugreek can add to the blood-sugar-lowering effect of diabetes drugs (EMA advises monitoring). Mild stomach and gut upset is the main side effect in trials.

Prediabetes: slowing the move to diabetes

Very low certainty

There are only a few trials in people with prediabetes. One 3-year trial reported fewer people moved on to diabetes on fenugreek, a 12-week extract trial lowered fasting and after-meal sugar, and a 6-month trial of a three-ingredient mix found no change. The best result comes from a trial without a proper placebo.

Studies, doses and limits

What the trials found

Gaddam 2015 randomized 140 adults (66 fenugreek, 74 matched controls) for 3 years; the authors reported fewer conversions to diabetes (controls had 4.2 times the chance), with lower fasting and after-meal glucose and lower LDL. The control group does not appear to have taken a placebo. Pickering 2022 gave 54 people a specialised extract for 12 weeks versus placebo: fasting glucose, after-meal glucose and triglycerides differed, but HbA1c, insulin and C-peptide did not. Florentin 2019 (100 people, 6 months) tested a mix of fenugreek, olive leaf and bergamot and found no change in HbA1c, fasting glucose, insulin, HOMA-IR or lipids. The 2017 review of food plants for impaired glucose tolerance (Demmers) judged its fenugreek evidence low quality. Kiss 2018 reported better glucose tolerance after fenugreek in healthy volunteers, with no numbers in the abstract.

Results

Mixed: one open 3-year trial and one small extract trial were positive, one mixed-herb trial was null. None shows prevention of diabetes in a blinded trial.

Effect sizes as reported

Gaddam 2015: controls 4.2 times more likely to develop diabetes. Pickering 2022: fasting glucose p<0.001, after-meal glucose p=0.007, HbA1c p=0.41.

Why this rating

Three small trials point different ways, the longest is not placebo-controlled, and the null trial used a mixed product.

Form and dose studied

Whole seed powder 10 g a day (Gaddam); a 500 mg a day extract (Pickering); a three-ingredient mix (Florentin).

Who was studied

Adults with prediabetes.

Limits

Few trials; no blinded long-term trial; one trial tested a mixture; the diabetes-prevention result may not hold with a placebo.

Why researchers looked

People with prediabetes would like a way to prevent type 2 diabetes.

Traditional use

Same traditional use for diabetes as above.

Proposed mechanism Preliminary mechanism

Possible effects on insulin release and on slowing sugar absorption (laboratory and animal work); not shown to be the reason for benefit in people.

A proposed mechanism does not show that the effect happens in people.

Mild stomach and gut upset is the usual side effect; seek advice if you also take diabetes drugs.

Blood sugar after a meal: fenugreek added to food

Low certainty

Adding fenugreek seed powder or flakes to bread or meals lowered the rise in blood sugar after the meal in small short trials in healthy people and in people with diabetes. These are very small tests of one or a few meals.

3 studiesFenugreek seed powder as 5% to 10% of flour in bread; 30 g a day of f…

Studies, doses and limits

What the trials found

Robert 2016: ten healthy adults ate buns and flatbreads with 10% of the flour replaced by fenugreek seed powder; the glycemic index of the buns fell from 82 to 51 and of the flatbread from 63 to 43. Losso 2009: eight people with diet-controlled diabetes ate bread with 5% fenugreek flour; insulin area under the curve was lower (p<0.05) but glucose area was not significantly lower. Deshpande 2025: 15 people with type 2 diabetes finished a crossover trial of 30 g a day of defatted fenugreek flakes for 14 days; 24-hour sugar rise (p=0.02) and glucose swings (p=0.006) were lower; three authors work for the sponsor. Sharma 1990 gave 100 g a day of defatted seed to people with type 1 diabetes for 10 days (see separate entry).

Results

Lower after-meal sugar rise with fenugreek-enriched foods in tiny trials; taste and food quality can suffer at higher amounts.

Effect sizes as reported

Robert 2016: glycemic index of buns 82 to 51 and flatbread 63 to 43 with 10% fenugreek. Deshpande 2025: 24-hour iAUC p=0.02.

Why this rating

Consistent direction in three small trials, but each had 8 to 21 people, tested a few meals or 14 days, and one is sponsor-linked.

Form and dose studied

Fenugreek seed powder as 5% to 10% of flour in bread; 30 g a day of flakes.

Who was studied

Healthy adults and adults with type 2 diabetes.

Limits

Very small; short; different foods; finger-prick blood samples in one trial; no long-term outcomes.

Why researchers looked

Fenugreek seed is rich in gum fibre, which thickens in the gut, so food makers have tried adding it to breads and flakes.

Traditional use

Fenugreek is eaten as a spice and as sprouted or ground seed in many cuisines.

Proposed mechanism Pharmacological theory

The gum fibre may slow digestion and absorption of sugar. Shown mainly in lab and food-science work; the human trials here did not test the mechanism.

A proposed mechanism does not show that the effect happens in people.

Fibre-rich products can cause wind or loose stools.

Insulin resistance and insulin levels

Mixed findings

Results are mixed. Some trials reported lower insulin and better insulin resistance scores (HOMA-IR), and one pooled analysis found no clear fall in HOMA-IR. Other trials found insulin went up, not down.

7 studiesWhole seed 10 g a day; extracts about 0.5 to 1 g a day; fibre 4 to 8 …

Studies, doses and limits

What the trials found

Kim 2023 pooled 10 trials and found no significant fall in HOMA-IR. Rafraf 2014 (88 people with type 2 diabetes, 10 g a day of whole seed for 8 weeks) reported lower insulin (p=0.03) and HOMA-IR (p=0.004) and higher adiponectin. Gupta 2001 (25 people, 1 g a day of extract) reported lower insulin area under the curve and better insulin sensitivity. Hota 2024 reported insulin lower by over 10% on a branded extract (unclear blinding). Najdi 2019 (9 finishers) saw insulin rise (p=0.04). Pickering 2022 found no change in fasting insulin (p=0.12). Mathern 2009 found an 8 g fibre dose raised the insulin response after a breakfast in obese adults.

Results

Mixed direction between trials; a pooled analysis found no clear fall in HOMA-IR.

Effect sizes as reported

Rafraf 2014: HOMA-IR p=0.004. Kim 2023: HOMA-IR not significant.

Why this rating

Trials disagree on whether insulin goes up or down, and the pooled result for HOMA-IR is null.

Form and dose studied

Whole seed 10 g a day; extracts about 0.5 to 1 g a day; fibre 4 to 8 g in one meal.

Who was studied

Adults with type 2 diabetes or prediabetes, healthy adults.

Limits

Different products, small samples, insulin is a lab marker rather than a symptom.

Why researchers looked

Insulin resistance underlies type 2 diabetes and many studies measure it.

Proposed mechanism Preliminary mechanism

In lab work an amino acid from the seed raises insulin release when sugar is high; effects on insulin resistance in people are unproven.

A proposed mechanism does not show that the effect happens in people.

None specific beyond the general safety section.

Cholesterol and blood fats

Low certainty

Pooled trials found small average falls in total cholesterol, LDL and triglycerides and a small rise in HDL after fenugreek seed products. The results come from small mixed-quality trials, many in people with diabetes, and the pooled results do not all agree.

10 studiesWhole seed or extract; amounts differ widely between trials.

Studies, doses and limits

What the trials found

Askarpour 2020 pooled 12 trials (560 people): total cholesterol -9.4 mg/dL, triglycerides -13.8 mg/dL, LDL -6.6 mg/dL, HDL +3.5 mg/dL; the LDL and triglyceride intervals came close to zero. Heshmat-Ghahdarijani 2020 pooled 15 trials and found falls in total cholesterol, LDL and triglycerides and a rise in HDL (units not stated in the abstract). Khodamoradi 2020: total cholesterol -9.1 mg/dL and LDL -11.1 mg/dL, no change in other measures. Gong 2016 found total cholesterol lower but triglycerides, LDL and HDL not clearly changed. Kim 2023 found total cholesterol, triglycerides and HDL improved but LDL did not. Fakhr 2023 (29 trials): triglycerides -20.1 mg/dL and HDL +3.6 mg/dL. Single trials: Pickering 2022 (triglycerides lower, total cholesterol/LDL/HDL not); Florentin 2019 (mixed product, no change); Geberemeskel 2019 (25 g twice a day for a month; large falls versus a metformin group). Rafraf 2014: total cholesterol and triglycerides lower, LDL and HDL not.

Results

Small average improvements in total cholesterol, triglycerides, and in some analyses LDL and HDL; analyses disagree on which markers move.

Effect sizes as reported

Askarpour 2020: TC -9.4 mg/dL, TG -13.8, LDL -6.6, HDL +3.5. Fakhr 2023: TG -20.12 mg/dL (-34.24 to -5.99), HDL +3.55 mg/dL.

Why this rating

Direction is mostly consistent across pooled analyses, but the effects are small, analyses disagree about LDL and triglycerides, trials are small and mostly low quality, and reviewers say trials in people with high blood fats are needed. No trial measured heart attacks or strokes.

Form and dose studied

Whole seed or extract; amounts differ widely between trials.

Who was studied

Mostly adults with type 2 diabetes or metabolic problems.

Limits

Mixed populations; short; results are blood tests, not heart outcomes.

Why researchers looked

Fenugreek is eaten as a fibre-rich seed that may bind bile acids, and trials often measured blood fats alongside blood sugar.

Traditional use

Used traditionally as a general tonic; claims about cholesterol come from modern study.

Proposed mechanism Animal research

Gum fibre may bind bile acids in the gut and the saponins may reduce cholesterol uptake. Shown in animals and lab work, not proven in people.

A proposed mechanism does not show that the effect happens in people.

No extra safety concerns beyond the general safety section.

Blood pressure

Very low certainty

Pooled trials found a small average fall in the top (systolic) blood pressure number of roughly 3 to 3.5 mmHg, and no clear fall in the bottom number. That is much smaller than a blood pressure pill.

3 studiesSeed amounts of 15 g a day or more in the subgroup that looked best (…

Studies, doses and limits

What the trials found

Amini 2023 pooled 6 trials (373 people) and found systolic pressure about 3.5 mmHg lower (CI -6.33 to -0.59) and diastolic pressure not clearly changed. Fakhr 2023 (29 trials) found systolic pressure 3.45 mmHg lower (CI -6.38 to -0.52) and diastolic pressure not significantly changed. Hadi 2020 (50 people with type 2 diabetes, 15 g a day for 8 weeks) saw a fall in systolic pressure within the fenugreek group.

Results

A small average fall in systolic pressure. No convincing fall in diastolic.

Effect sizes as reported

Fakhr 2023: SBP -3.45 mmHg (-6.38 to -0.52); DBP not significant. Amini 2023: SBP about -3.5 mmHg.

Why this rating

The effect is small, the intervals come close to zero, few trials measured pressure carefully, and the amounts and durations vary. One pooled analysis printed its sign inconsistently in the abstract.

Form and dose studied

Seed amounts of 15 g a day or more in the subgroup that looked best (Amini 2023).

Who was studied

Adults, often with diabetes or metabolic problems.

Limits

Only 6 trials in one analysis; blood pressure not the main aim of most trials.

Why researchers looked

Blood pressure was measured in trials of people with metabolic problems.

Proposed mechanism Preliminary mechanism

No clear mechanism has been shown in people.

A proposed mechanism does not show that the effect happens in people.

People on blood pressure drugs should not stop them. Fenugreek has not been tested as a blood pressure treatment.

Weight loss (body weight and BMI)

Evidence against

Pooled analyses found no change in body weight or BMI after fenugreek. Waist size was a little smaller in one analysis. Fenugreek has not been shown to help people lose weight.

3 studiesVarious.

Studies, doses and limits

What the trials found

Askarpour 2020 (12 trials): body weight +0.22 kg (CI -0.51 to 0.96) and BMI +0.09 (CI -0.24 to 0.43), no change. Fakhr 2023 (29 trials): BMI -0.40 kg/m2 (CI -1.11 to 0.32), not significant; waist circumference 2.5 units smaller (CI -3.78 to -1.24). Kim 2023: BMI did not change. Hadi and Pickering found no weight changes in their trials.

Results

No effect on body weight or BMI; a small fall in waist size in one analysis.

Effect sizes as reported

Askarpour 2020: weight +0.223 kg (-0.509 to 0.955); BMI +0.091 (-0.244 to 0.426). Fakhr 2023: waist -2.51 (-3.78 to -1.24).

Why this rating

Three pooled analyses found no change in weight or BMI.

Form and dose studied

Various.

Who was studied

Adults.

Limits

Waist result from one analysis only; follow-up short.

Why researchers looked

Fenugreek fibre may make people feel full, so weight was tested.

Traditional use

Sometimes marketed for weight loss.

Proposed mechanism Pharmacological theory

Fibre may increase fullness; see the appetite entry for the small trials.

A proposed mechanism does not show that the effect happens in people.

Do not use fenugreek for weight loss in place of medical care.

Fatty liver disease

Not enough evidence

One small pilot trial of 30 people found no difference from placebo. That is the only trial read, so there is not enough evidence.

1 studies1 g a day of a hydroalcoholic seed extract.

Studies, doses and limits

What the trials found

Babaei 2020 randomized 30 adults with fatty liver disease (24 finished) to 1 g a day of seed extract or placebo for 3 months. Changes in ALT, scan scores, liver stiffness and weight did not differ between the groups. A 2026 network meta-analysis of plant extracts for fatty liver exists in PubMed but was not read.

Results

No benefit detected in one small pilot trial.

Effect sizes as reported

No significant differences.

Why this rating

One pilot trial with 30 people could miss a modest effect.

Form and dose studied

1 g a day of a hydroalcoholic seed extract.

Who was studied

Adults with fatty liver disease.

Limits

Tiny sample; short.

Why researchers looked

Fatty liver is linked to diabetes and high cholesterol, which fenugreek has been tested in.

Proposed mechanism Preliminary mechanism

No mechanism shown in people.

A proposed mechanism does not show that the effect happens in people.

No liver harm was seen in this trial. See the liver section of the safety file.

Type 1 diabetes

Not enough evidence

The only trial read is a small 1990 study using a very large food-level amount of defatted seed for 10 days. It reported lower blood sugar and cholesterol. This is too little evidence, and fenugreek must never replace insulin.

1 studies100 g of defatted seed powder a day, split into two meals (this is fa…

Studies, doses and limits

What the trials found

Sharma 1990 gave people with insulin-dependent (type 1) diabetes isocaloric diets with and without 100 g a day of defatted fenugreek seed powder for 10 days each, in random order. The abstract reports lower fasting blood sugar, better glucose tolerance, 54% less sugar lost in the urine over 24 hours, and lower total, LDL and VLDL cholesterol and triglycerides; HDL did not change. The number of people is not stated.

Results

Reported improvement in a short 1990 trial; no newer trial was found.

Effect sizes as reported

24-hour urine glucose down 54%.

Why this rating

One old short trial of unstated size with a very large amount of seed.

Form and dose studied

100 g of defatted seed powder a day, split into two meals (this is far above normal food use).

Who was studied

People with type 1 diabetes.

Limits

Old, small, short; the dose is a very large food amount.

Why researchers looked

Early research tested fenugreek in people who need insulin.

Traditional use

Traditional use for diabetes in general.

Proposed mechanism Preliminary mechanism

No mechanism shown in people.

A proposed mechanism does not show that the effect happens in people.

People who use insulin could have low blood sugar if they change their diet or add fenugreek; talk to a doctor first.

Testosterone levels in men

Very low certainty

Pooled analyses find a small average rise in total testosterone with fenugreek extracts, but the best 2026 analysis rates the evidence very low in certainty, found no clear change in free testosterone, and says it does not support testosterone-boosting claims. Several trials were small or run by the product makers.

9 studiesBranded seed extracts (for example Testofen, Furosap, Fenu-FG, Trigoz…

Studies, doses and limits

What the trials found

Yang 2026 (13 randomized placebo-controlled trials; 6 in the total-testosterone analysis) found a small favourable effect on total testosterone (SMD 0.25, CI 0.02 to 0.48, I2 0%) and no clear effect on free testosterone (SMD 0.08, CI -0.48 to 0.63, I2 66.7%); none of the 13 trials was low risk of bias and certainty was very low (GRADE). Mansoori 2020 (4 trials) reported a significant effect on total testosterone with no numbers in the abstract. Isenmann 2023 (7 studies, 449 people, mostly male athletes) found total testosterone SMD 0.32 (CI 0.09 to 0.55) and free testosterone SMD 0.24 (CI -0.04 to 0.52). Smith 2021 (32 herb trials in men) named fenugreek seed extracts and ashwagandha as having positive effects, and noted only 6 of 32 studies had low risk of bias. Individual trials: Lee-Ødegård 2024 (95 men aged 40 to 80, 12 weeks, extract with essential nutrients) found blood total testosterone up 9.0% versus placebo (not significant) but saliva testosterone up 37.2% versus placebo (p=0.042); that trial was run by its funder. Wankhede 2016 (60 men, 8 weeks of resistance training) reported higher testosterone on a glycoside fraction. Rao 2020 (100 men with prostate enlargement) found hormones unchanged. Furosap studies (50 and 100 men, open-label, no control group) reported testosterone rises but cannot show cause; their authors are linked to the extract developer.

Results

A small average rise in total testosterone in healthy or recreationally active men; free testosterone not clearly changed.

Effect sizes as reported

Yang 2026: total T SMD 0.25 (0.02 to 0.48); free T SMD 0.08 (-0.48 to 0.63). Isenmann 2023: total T SMD 0.32 (0.09 to 0.55).

Why this rating

The reviewers of the newest analysis rate it very low certainty; none of 13 trials was low risk of bias; many trials are of branded extracts and some are sponsored or open-label.

Form and dose studied

Branded seed extracts (for example Testofen, Furosap, Fenu-FG, Trigozim), about 300 to 1,800 mg a day in the trials read. Not comparable between products.

Who was studied

Mostly healthy younger or middle-aged men; few men with confirmed low testosterone.

Limits

Small trials, product-linked authors, free testosterone unclear, no trial of men with low testosterone and symptoms.

Why researchers looked

Fenugreek saponins such as protodioscin and diosgenin are marketed as testosterone supports, so many branded extracts were tested.

Traditional use

Fenugreek is used in traditional medicine for male and female reproductive health (a narrative review, Sun 2021).

Proposed mechanism Pharmacological theory

The proposed idea is that saponins affect the enzymes that break down testosterone or its conversion. The EMA draft notes only animal reproductive toxicity. No mechanism has been shown in men.

A proposed mechanism does not show that the effect happens in people.

Case reports of lung blood clots in men taking fenugreek-containing testosterone supplements exist (see safety file); cause is unproven.

Male libido and sexual wellbeing

Low certainty

Two small placebo-controlled trials in healthy men reported better libido scores or "aging male" symptom scores. Open-label studies reported better sexual health but cannot show cause. The newest analysis says current evidence does not support testosterone-boosting or sexual claims.

5 studiesTestofen 600 mg a day; seed extract 400 or 500 mg a day.

Studies, doses and limits

What the trials found

Steels 2011 randomized 60 healthy men aged 25 to 52 (no erectile dysfunction) to Testofen (fenugreek extract plus minerals; 600 mg a day) or placebo for 6 weeks: sexual arousal and orgasm scores improved, mood and sleep did not, and testosterone and prolactin stayed in range. Hausenblas 2020 (57 healthy young men, 400 or 500 mg a day for 60 days) reported better aging-male symptoms, anxiety, grip strength and quality of life; the abstract gives no numbers. Maheshwari 2017 and Sankhwar 2023 (open-label, no control group, extract developer-linked) reported improved libido and sexual health. Yang 2026 descriptively summarised sexual function across trials and concluded the evidence does not support commercial claims.

Results

Reported improvements in libido questionnaires in two small trials of healthy men.

Effect sizes as reported

Steels 2011: sexual arousal and orgasm domains significantly higher than placebo (numbers not in abstract).

Why this rating

Two placebo-controlled trials point the same way, but both are small, short, in healthy men and use branded extracts; open-label studies add little.

Form and dose studied

Testofen 600 mg a day; seed extract 400 or 500 mg a day.

Who was studied

Healthy men, ages 25 to 52 in the placebo trials.

Limits

Healthy volunteers, not men with sexual problems; no numbers in abstracts; self-reported scores.

Why researchers looked

Fenugreek is sold for male vitality.

Traditional use

Traditional use for reproductive health.

Proposed mechanism Pharmacological theory

Unknown. The idea that it works through testosterone is not confirmed.

A proposed mechanism does not show that the effect happens in people.

Women: sexual desire and arousal

Very low certainty

One 8-week placebo-controlled trial of 80 healthy women with low sexual drive reported higher desire and arousal scores and a rise in free testosterone and estradiol. No other trial was found.

1 studiesLibifem 600 mg a day for 8 weeks.

Studies, doses and limits

What the trials found

Rao 2015 randomized 80 healthy menstruating women aged 20 to 49 with low sexual drive to 600 mg a day of the extract Libifem or placebo for two menstrual cycles. Free testosterone and estradiol rose, and sexual desire and arousal were higher than with placebo.

Results

Higher desire and arousal scores in one trial; changes in sex hormones.

Effect sizes as reported

Significant increases in free testosterone, estradiol, desire and arousal (numbers not in abstract).

Why this rating

One small trial of a branded extract; no replication.

Form and dose studied

Libifem 600 mg a day for 8 weeks.

Who was studied

Healthy menstruating women aged 20 to 49 reporting low sexual drive.

Limits

Single site; short; abstract gives no numbers. A rise in estradiol and testosterone is a hormone effect.

Why researchers looked

Fenugreek extract was tested for effects on sex hormones in women.

Traditional use

Traditional use for female reproductive health.

Proposed mechanism Preliminary mechanism

Unknown; the hormone changes seen in this trial are not a proven reason for the benefit.

A proposed mechanism does not show that the effect happens in people.

Hormone changes mean women with hormone-sensitive conditions should ask a doctor first.

Studies, doses and limits

What the trials found

Isenmann 2023 pooled 7 studies (449 people, 378 men): lean body mass SMD 0.19 (CI -0.10 to 0.49), fat mass SMD -0.19 (CI -0.44 to 0.05) and leg press SMD 0.22 (CI -0.02 to 0.47), all with intervals that include zero. Albaker 2023 reviewed 6 trials: four reported better strength, endurance, lean mass or body fat, two small trials (under 10 people) were weak. Wankhede 2016 (60 men, 8 weeks of resistance training) reported better body fat without loss of strength. Hausenblas 2020 reported better grip strength in healthy men.

Results

Small hints of benefit not confirmed by pooled intervals.

Effect sizes as reported

Isenmann 2023: lean mass SMD 0.19 (-0.10 to 0.49); leg press 0.22 (-0.02 to 0.47).

Why this rating

Intervals include zero for strength and body composition; trials small and short; branded extracts.

Form and dose studied

Seed extracts and glycoside fractions (about 600 mg a day in the trial read in more detail).

Who was studied

Mostly young male recreational athletes.

Limits

Few women; sponsor ties; short; The review of Albaker notes doping and kidney or liver concerns need awareness.

Why researchers looked

Fenugreek glycosides are marketed to athletes.

Proposed mechanism Pharmacological theory

Possible hormone effect (unproven).

A proposed mechanism does not show that the effect happens in people.

Breast milk supply

Very low certainty

Fenugreek is widely used by breastfeeding mothers to boost milk, but the evidence is very uncertain. A Cochrane review rated the evidence low to very low, small trials of fenugreek tea or capsules reported more milk, and a trial of cookies found no effect. LactMed notes the effect may be mostly psychological and that safety data are limited.

9 studiesTea, capsules (500 mg three times a day in one trial), mixtures and c…

Studies, doses and limits

What the trials found

The Cochrane review (Foong 2020; 41 trials, 3,005 mothers) found natural galactagogues including fenugreek too varied to pool; certainty low to very low; it is very uncertain whether fenugreek improves infant weight. Khan 2018 (network analysis, 5 studies, 122 women on fenugreek) found more milk than placebo but less than Coleus amboinicus and palm date. Mortel 2013 (6 trials of herbs) made no recommendation to use herbs. Trials: Turkyilmaz 2011 (66 mothers, herbal tea containing fenugreek) found more milk on day 3 and quicker regain of birth weight. Rouhi 2025 (68 mothers of preterm babies, 500 mg three times a day) found more milk on day 7 but no difference by day 15 and no change in prolactin. Bumrungpert 2018 (50 mothers, fenugreek-ginger-turmeric mixture) found milk volume up 49% at week 2 and 103% at week 4. Palacios 2023 (176 parents, cookies with fenugreek and other ingredients) found no effect. Wagner 2019 (60 mothers) tested the safety of a multi-herb tea and found no adverse effects attributable to it.

Results

Some small trials show more milk; the best-quality review rates the evidence very uncertain; one trial with food-type use found no effect.

Effect sizes as reported

Khan 2018 (network analysis): fenugreek versus placebo 11.11 (CI 6.77 to 15.46; units not given). Palacios 2023: milk production difference -0.33 mL/h (not significant).

Why this rating

Cochrane rates certainty low to very low; trials are small, short, often combine herbs and measure milk in different ways.

Form and dose studied

Tea, capsules (500 mg three times a day in one trial), mixtures and cookies.

Who was studied

Breastfeeding mothers, including mothers of preterm babies.

Limits

Mixed products; short follow-up; effect on infant growth unclear.

Why researchers looked

Fenugreek is one of the most common traditional milk boosters worldwide.

Traditional use

Used in many regions to increase milk supply (LactMed).

Proposed mechanism Preliminary mechanism

Proposed effects on insulin, prolactin and oxytocin are reported in some studies but are not established; LactMed says the effect may be mostly psychological.

A proposed mechanism does not show that the effect happens in people.

Studies, doses and limits

What the trials found

Hassanzadeh 2024 (4 trials) found pain lower than placebo (SMD -2.21, CI -3.26 to -1.17) and no difference from mefenamic acid; GRADE low quality, effect "highly uncertain". The Cochrane review (Pattanittum 2016; 27 trials of supplements) judged all evidence low or very low; for fenugreek one trial of 101 women gave very limited evidence (-1.71 points on a 0 to 10 scale, CI -2.35 to -1.07). Younesy 2014 (101 students, 900 mg capsules, 2 to 3 three times a day for the first three days of the period, 2 cycles) found larger pain reduction than placebo (p<0.001). Inanmdar 2016 (60 women, open-label) found pain down about 66.9% with 3 g twice a day, 66.5% with cupping added and 62.9% with mefenamic acid.

Results

Less period pain than placebo in small trials; similar to mefenamic acid in two comparisons.

Effect sizes as reported

Hassanzadeh 2024: SMD -2.21 (-3.26 to -1.17) versus placebo. Cochrane: -1.71 points (-2.35 to -1.07), one trial.

Why this rating

GRADE low in the 2024 analysis; Cochrane very limited; students in Iran and India; the open trial had no placebo.

Form and dose studied

Seed powder capsules taken in the first days of the period (900 mg capsules, or 3 g twice a day, in the trials).

Who was studied

Young women with primary period pain.

Limits

Few trials; one-country; open-label trial included.

Why researchers looked

Fenugreek seed is a traditional remedy for period pain.

Traditional use

Traditional use in Iranian and Unani medicine (the trials come from these traditions).

Proposed mechanism Preliminary mechanism

Possible anti-inflammatory action (lab and animal ideas only).

A proposed mechanism does not show that the effect happens in people.

Not for use in pregnancy (see safety file). Pain that is severe or new needs a doctor.

Menopause symptoms (hot flushes, night sweats, mood)

Low certainty

Three small placebo-controlled trials of branded extracts in women around menopause reported fewer hot flushes and night sweats and better scores for mood and quality of life. Two of them also saw rises in estradiol. None has been replicated by an independent team.

4 studiesExtracts of 250 to 1,000 mg a day for 6 to 13 weeks.

Studies, doses and limits

What the trials found

Steels 2017 (115 women aged 40 to 65, 600 mg a day de-husked seed extract, 12 weeks) found better total menopause quality-of-life scores and fewer hot flushes and night sweats than placebo; estradiol did not differ. Begum 2016 (88 women, 1000 mg a day husk extract, 90 days) found plasma estradiol up 120% and better symptoms; 32% reported no hot flashes afterwards. Khanna 2020 (48 women, 250 mg twice a day, 42 days) reported hot flashes down 25.9%, night sweats 26.5%, depression 31.8%, insomnia 21.6%, with estradiol up 18.9% and FSH down 38.2%. Safary 2020 (60 postmenopausal women) found a fenugreek vaginal cream improved signs of vaginal thinning but less than a low-dose estrogen cream.

Results

Fewer hot flushes and better symptom scores than placebo in three small trials of three different branded extracts.

Effect sizes as reported

Khanna 2020: hot flashes -25.9%, night sweats -26.5% (within the extract group, 6 weeks). Begum 2016: estradiol +120%.

Why this rating

Consistent direction in three placebo-controlled trials, but each has 24 to 59 per group, a different extract, short duration and no independent replication.

Form and dose studied

Extracts of 250 to 1,000 mg a day for 6 to 13 weeks.

Who was studied

Women with menopause symptoms.

Limits

Different products; self-reported scores; a big rise in estradiol in one trial is itself a safety question.

Why researchers looked

Fenugreek extracts are marketed for women in menopause.

Traditional use

Traditional use for female hormone health.

Proposed mechanism Preliminary mechanism

Some trials report changes in estradiol, testosterone, FSH and SHBG; the clinical meaning is unclear.

A proposed mechanism does not show that the effect happens in people.

Women with breast or other hormone-sensitive cancers or conditions should ask their doctor before using fenugreek extracts.

Polycystic ovary syndrome (PCOS)

Very low certainty

Studies of one patented extract (Furocyst) reported smaller ovarian cysts and more regular periods, but two of the three studies had no placebo group and all are from the product developers.

3 studiesFurocyst 1000 mg a day for 90 days or 12 weeks.

Studies, doses and limits

What the trials found

Swaroop 2015 (50 women, open-label, no control, 90 days) reported smaller ovary volume, cysts shrinking in about 46% and 71% reporting regular cycles. Sankhwar 2023 (107 women, single group, 12 weeks) reported over 40% smaller cysts. Singh 2023 (208 women, double-blind versus placebo) reported fewer cysts, smaller ovaries, less hirsutism and lower free testosterone; the abstract gives no numbers.

Results

Reported improvement in cysts, hormones and periods from one product.

Effect sizes as reported

Swaroop 2015: 71% reported return of regular cycle; no control group.

Why this rating

One branded extract, trials from the developer group, two without a control group, abstract of the randomized trial gives no numbers.

Form and dose studied

Furocyst 1000 mg a day for 90 days or 12 weeks.

Who was studied

Premenopausal women with PCOS.

Limits

No independent trial; not compared with standard PCOS care.

Why researchers looked

A branded fenugreek extract was developed for PCOS.

Proposed mechanism Preliminary mechanism

Unknown.

A proposed mechanism does not show that the effect happens in people.

PCOS needs medical care; do not replace treatment.

Appetite, fullness and fat intake

Very low certainty

Tiny short trials suggest fenugreek fibre may make people feel fuller and a seed extract may slightly lower the fat people eat, but weight did not change.

3 studiesIsolated fibre 4 to 8 g in one meal; extract 588 to 1176 mg a day.

Studies, doses and limits

What the trials found

Mathern 2009 (18 obese adults, crossover) found 8 g of isolated fenugreek fibre increased fullness and lowered hunger after breakfast; lunch intake was lower than after 4 g but not significantly lower than control; taste ratings fell as the fibre dose rose. Chevassus 2009 (12 healthy men, 588 or 1176 mg a day, crossover) found the higher dose cut daily fat intake by 17.3% (p=0.038). Chevassus 2010 (39 overweight men, 6 weeks) found a slight fall in fat intake relative to energy expenditure (0.26 vs 0.30, p=0.032) but no effect on weight or appetite scores. Note the EMA monograph lists temporary loss of appetite as a traditional use for fenugreek, the opposite direction, so the effect on appetite is unclear.

Results

Small short-term effects on fullness and fat intake; weight unchanged.

Effect sizes as reported

Chevassus 2009: fat intake -17.3% (CI for MJ/day difference -1.51 to -0.05).

Why this rating

Three tiny trials, men only, short; appetite findings conflict with traditional appetite-stimulating use.

Form and dose studied

Isolated fibre 4 to 8 g in one meal; extract 588 to 1176 mg a day.

Who was studied

Obese adults, healthy and overweight men.

Limits

Tiny, short, men only.

Why researchers looked

The seed fibre swells and may fill the stomach.

Traditional use

Fenugreek is eaten as a spice and is also taken to stimulate appetite (the EMA monograph lists traditional use for temporary loss of appetite).

Proposed mechanism Pharmacological theory

Fibre may slow stomach emptying; extracts may change eating behaviour; mostly animal and theoretical.

A proposed mechanism does not show that the effect happens in people.

Fibre can cause wind and loose stools.

Prostate enlargement symptoms

Not enough evidence

One 12-week placebo-controlled trial of 100 men with prostate enlargement symptoms found no improvement.

1 studies600 mg a day extract.

Studies, doses and limits

What the trials found

Rao 2020 randomized 100 men aged 45 to 80 with prostate symptoms (score of at least 8) to 600 mg a day of a standardised extract or placebo for 12 weeks: symptoms did not improve, and hormones, PSA and safety markers stayed unchanged.

Results

No benefit for prostate symptoms.

Effect sizes as reported

No effect on International Prostate Symptom Score.

Why this rating

One trial, null result.

Form and dose studied

600 mg a day extract.

Who was studied

Men with benign prostate enlargement.

Limits

One trial.

Why researchers looked

Fenugreek extract was tested in men with benign prostate enlargement.

Proposed mechanism Preliminary mechanism

None shown.

A proposed mechanism does not show that the effect happens in people.

PSA stayed unchanged in this trial.

Studies, doses and limits

What the trials found

Foroumandi 2023 (82 people with mild to moderate Alzheimer's in care homes, 5 cc of seed extract for 4 months versus placebo) reported higher memory and quality-of-life scores, lower depression and blood pressure, and better antioxidant markers compared with their own baselines. Nathan 2014 (50 people with Parkinson's on L-dopa, 300 mg of extract twice a day for 6 months versus placebo) reported a slower rise in total UPDRS score (0.098% vs 13.36%) and good safety.

Results

Reported benefits in two preliminary trials.

Effect sizes as reported

Nathan 2014: UPDRS rose 0.098% (extract) vs 13.36% (placebo).

Why this rating

Two small trials of different extracts, one with within-group comparisons; no replication.

Form and dose studied

5 cc extract daily (Alzheimer's trial); 300 mg twice a day (Parkinson's trial).

Who was studied

People with Alzheimer's or Parkinson's.

Limits

Preliminary; do not substitute for medicines.

Why researchers looked

Fenugreek has antioxidant compounds studied in brain-disease models.

Proposed mechanism Animal research

Mostly animal and lab ideas (antioxidant action, trigonelline); not proven in people.

A proposed mechanism does not show that the effect happens in people.

Blood Sugar Balance Potential benefit Low certainty Type 2 diabetes: blood sugar and HbA1c: Pooled analyses of small trials usually find that fenugreek seed products lower fasting blood sugar and HbA1c a little in people with type 2 diabetes. But the trials are small, short, of mixed quality and disagree a lot, and one 2023 analysis found no clear fall in fasting sugar. The US National Center for Complementary and Integrative Health says there is not enough high-quality evidence to say whether fenugreek helps diabetes. Prediabetes: slowing the move to diabetes: There are only a few trials in people with prediabetes. One 3-year trial reported fewer people moved on to diabetes on fenugreek, a 12-week extract trial lowered fasting and after-meal sugar, and a 6-month trial of a three-ingredient mix found no change.

Cholesterol Balance Potential benefit Low certainty Cholesterol and blood fats: Pooled trials found small average falls in total cholesterol, LDL and triglycerides and a small rise in HDL after fenugreek seed products. The results come from small mixed-quality trials, many in people with diabetes, and the pooled results do not all agree. 8 37 45 31 46 25 67 26 30 69

The results come from small mixed-quality trials, many in people with diabetes, and the pooled results do not all agree. Blood pressure: Pooled trials found a small average fall in the top (systolic) blood pressure number of roughly 3 to 3.5 mmHg, and no clear fall in the bottom number. That is much smaller than a blood pressure pill. 8 37 45 31 46 25 67 26 30 69 6 33

Weight Management Potential benefit Evidence against Weight loss (body weight and BMI): Pooled analyses found no change in body weight or BMI after fenugreek. Waist size was a little smaller in one analysis. Fenugreek has not been shown to help people lose weight. Appetite, fullness and fat intake: Tiny short trials suggest fenugreek fibre may make people feel fuller and a seed extract may slightly lower the fat people eat, but weight did not change. 8 25 46 55 18 19
Liver Support Potential benefit Not enough evidence Fatty liver disease: One small pilot trial of 30 people found no difference from placebo. That is the only trial read, so there is not enough evidence. 10
Mens Vitality Potential benefit Very low certainty Testosterone levels in men: Pooled analyses find a small average rise in total testosterone with fenugreek extracts, but the best 2026 analysis rates the evidence very low in certainty, found no clear change in free testosterone, and says it does not support testosterone-boosting claims. Several trials were small or run by the product makers. Male libido and sexual wellbeing: Two small placebo-controlled trials in healthy men reported better libido scores or "aging male" symptom scores. Open-label studies reported better sexual health but cannot show cause. The newest analysis says current evidence does not support testosterone-boosting or sexual claims. 92 54 40 82 51 90 71 53 75 83 35

Open-label studies reported better sexual health but cannot show cause. The newest analysis says current evidence does not support testosterone-boosting or sexual claims. Women: sexual desire and arousal: One 8-week placebo-controlled trial of 80 healthy women with low sexual drive reported higher desire and arousal scores and a rise in free testosterone and estradiol. No other trial was found. 83 35 53 75 92 70
Womens Wellness Potential benefit Very low certainty Women: sexual desire and arousal: One 8-week placebo-controlled trial of 80 healthy women with low sexual drive reported higher desire and arousal scores and a rise in free testosterone and estradiol. No other trial was found. Breast milk supply: Fenugreek is widely used by breastfeeding mothers to boost milk, but the evidence is very uncertain. A Cochrane review rated the evidence low to very low, small trials of fenugreek tea or capsules reported more milk, and a trial of cookies found no effect. LactMed notes the effect may be mostly psychological and that safety data are limited. 70 27 43 58 88 73 15 64 89 1 34 66 93 39 84 79 44 74 87 81 76

Menopause Support Potential benefit Low certainty Menopause symptoms (hot flushes, night sweats, mood): Three small placebo-controlled trials of branded extracts in women around menopause reported fewer hot flushes and night sweats and better scores for mood and quality of life. Two of them also saw rises in estradiol. None has been replicated by an independent team. 84 79 44 74
Mood Balance Potential benefit Low certainty Menopause symptoms (hot flushes, night sweats, mood): Three small placebo-controlled trials of branded extracts in women around menopause reported fewer hot flushes and night sweats and better scores for mood and quality of life.

Bars show how many studies we found for each outcome, not how well it works. People are added up across trials only (reviews are not added, to avoid double counting).

How we rate evidence

High certainty

Several well-run trials or reviews agree; further research is unlikely to change the picture much.

Moderate certainty

Good trials point the same way, but some doubt remains.

Low certainty

Small, short or inconsistent trials. The finding could change with better research.

Very low certainty

Very little or very weak human data. Treat as a possibility only.

Mixed findings

Trials or reviews disagree with each other.

Not enough evidence

Not enough human research to say either way.

Evidence against

Good research found no benefit, or found harm.

We take the reviewers' own risk-of-bias and GRADE statements where they exist, and otherwise judge from study size, design, consistency, directness and whether a product matches what is sold. Many publications do not make evidence high. Method note: We searched PubMed, read the full text of the EU draft herbal monograph on fenugreek seed (revision 1, March 2021) and the US National Center for Complementary and Integrative Health page, read the LactMed entry through its PubMed record, and checked plant names in GBIF and the NCBI taxonomy and compounds in PubChem. Only abstracts were read for almost all studies. Some sources were not verified: LiverTox (it could not be opened), the final adopted EU monograph (the draft was read), the German Commission E monograph, and the WHO and FDA statements. Certainty ratings are the compiler's own reading, except where the reviewers gave their own (the 2026 testosterone review rates its evidence very low by GRADE; the 2024 dysmenorrhea review rates it low by GRADE). No study is cited that we could not verify.

Breastfeeding mothers and infants Fenugreek seed as a milk booster
seed Usual amounts quoted: 1 to 6 g a day for milk supply
LactMed (US National Library of Medicine) notes limited safety data; stomach and gut effects, allergy, asthma worsening and maple-syrup odour of urine, sweat and possibly breastmilk; 43% of 122 mothers thought it helped milk supply and 5% thought it hurt; caution with diabetes and warfarin.
Methods, limits and funding

Outcomes: Safety in breastfeeding

Limitations: Database entry; no named authors. The text reports a survey where 45% of 85 mothers had an adverse reaction (as printed).

Fenugreek (various)
seed Various Various · vs Control groups
Only HbA1c showed a clear fall. Fasting and after-meal glucose were not clearly changed in the pooled numbers. The authors flag low study quality and big differences between trials.
HbA1c MD -0.88; fasting glucose MD 3.70 (as printed); postprandial glucose MD -10.61 (HbA1c -1.49 to -0.27; fasting -27.02 to 19.62 (p 0.76); postprandial -68.48 to 47.26 (p 0.72))
Methods, limits and funding

Outcomes: Fasting glucose, postprandial glucose, HbA1c

Limitations: Abstract only. The abstract describes the fasting result as a reduction but prints a positive mean difference of 3.70 with a confidence interval that crosses zero; we report the numbers as printed and do not treat fasting glucose as shown by this review.

What we do not know yet

  • What the evidence supports: nothing is rated above low. Type 2 diabetes blood sugar, cholesterol, after-meal sugar from foods, menstrual pain, menopause symptoms and male libido are low; testosterone, milk supply, blood pressure and several others are very low; insulin resistance is mixed; weight is against; fatty liver, type 1 diabetes, prostate symptoms and brain conditions are insufficient.
  • What is uncertain: most trials are small, short, of low quality and use very different products (whole seed, extracts, fibre, mixtures), so results cannot be moved between products. Many extract trials come from the product developers or are open-label. Pooled analyses disagree on fasting blood sugar and LDL.
  • What has never been tested: whether fenugreek prevents diabetes complications, heart attacks or fractures; trials in men with confirmed low testosterone; any human trial of the leaf; fenugreek with aspirin or newer blood thinners; long-term safety of extracts; safety in pregnancy in people; and contamination of supplements with metals or pesticides.
  • What we could not verify: LiverTox (the page could not be opened), the final adopted EU monograph of November 2021 (the March 2021 draft was read in full), the German Commission E and WHO statements, and the FDA position known only through LactMed. LactMed's own cited references were not read.
  • Almost all studies were read as abstracts only, and several abstracts give no numbers or print them inconsistently, so we report only what they state.

How new research is added

New studies are found by a saved PubMed search and are placed in a review queue. A person reads each one before it changes any evidence rating or safety wording. New publications never change ratings automatically.

Lab markers

What changed in blood or saliva tests during trials. A changed number is not the same as feeling or being healthier, and we give no "normal ranges".

Fasting blood glucose

Lowered in trials

The sugar level in blood after not eating overnight.

Low certainty
Results and what it means

Why it was measured

Main blood sugar measure in fenugreek trials.

Statistical vs. clinical meaning

Average falls of about 15 to 20 mg/dL in several analyses are statistically clear, but disagreement between trials is high and one analysis found no clear fall. A lab change does not show fewer diabetes complications.

Safety implication

May add to the blood-sugar-lowering of diabetes drugs.

HbA1c (average blood sugar over about 3 months)

Lowered in trials

A blood test that reflects average blood sugar over roughly the last three months.

Low certainty
Results and what it means

Why it was measured

Shows longer-term blood sugar control.

Statistical vs. clinical meaning

A fall of 0.6 to 0.9 points would matter if real, but it comes from few trials of mixed quality, and the real size is uncertain. NCCIH says evidence is not strong enough.

Safety implication

Safety

What studies and official sources say about side effects, medicines and who should check first. Each point shows what kind of evidence it comes from.

Main points to know 9
  • Fenugreek can make sweat, urine and breath smell of maple syrup, and can cause a false alarm for a rare newborn disease. Fenugreek by mouth can give urine, sweat and skin a maple-syrup smell. This is harmless in itself. But the same smell is the sign of maple syrup urine disease, a rare inherited illness of newborns. Mothers who took fenugreek during labour had newborns who smelled of maple syrup, which led to a false suspicion of the disease. The lab compound sotolone is shared by fenugreek and by the urine of patients with the disease. A mother taking fenugreek, or a baby of a mother who took it, should tell doctors and nurses so the smell is not misread; and a baby who is unwell should always be seen, whatever the smell. A separate study of armpit sweat found other compounds (such as 2,5-dimethylpyrazine) appeared after fenugreek and gave the best-matching smell. Case report 48 11 57 68 56 7 27 1
  • It may lower blood sugar, and can add to diabetes medicines. Fenugreek seed products can lower blood sugar. The EU herbal monograph (draft Revision 1) says close monitoring of blood sugar control should be considered in people treated for diabetes. NCCIH says large amounts may cause a harmful drop in blood sugar, and LactMed advises caution at high doses in women with diabetes. Trials in people on metformin or sulfonylureas did not report severe lows in their abstracts, but they were small. A scoping review of 60 articles lists hypoglycemia among reported effects. People on insulin or diabetes pills should not add fenugreek without telling their doctor, and should know the signs of low blood sugar. Authoritative guidance 95 99 1 7 38 33
  • Do not use medicinal amounts in pregnancy. The EU monograph says use in pregnancy, in breastfeeding and in women who could become pregnant and are not using contraception is not recommended: animal studies show reproductive toxicity, including effects on male and female fertility. NCCIH says fenugreek is not safe in pregnancy in amounts larger than found in food and that use has been linked to a higher risk of birth defects. A toxicology review (mostly animal data) reports birth defects, embryo loss and anti-implantation or abortion-causing activity in animals and advises against use in pregnancy. We found no controlled human study of fenugreek in pregnancy. Culinary amounts are different from medicinal amounts. Authoritative guidance 95 99 63
  • Allergy: people with peanut, soya, chickpea or other legume allergy can react, sometimes severely. Fenugreek is a legume. Proteins in it resemble major peanut allergens (Ara h 1 and Ara h 3), and most blood samples from peanut-allergic patients in one study also showed IgE to fenugreek, so cross-reaction is likely. Case reports describe wheezing, fainting, facial swelling, anaphylaxis (including in a child) and, in one new mother, toxic epidermal necrolysis, a severe blistering skin reaction. The EU monograph lists hypersensitivity to fenugreek, peanut, soya and other legumes as a contraindication. In one challenge about 2 mg of fenugreek powder produced objective symptoms. Allergic reactions have been reported after skin use and after inhaling the powder. Authoritative guidance 95 65 42 9 17 23 24 12
  • Blood thinners: a possible increase in bleeding with warfarin. One woman on warfarin had a rise in her INR (blood-thinning level) that fell when she stopped boldo and fenugreek and rose again when both were restarted; the authors rated the link probable but two herbs were involved. Reviews list fenugreek among herbs that may add to warfarin, but note that most such information is from single cases, lab work or animals. People on warfarin or other blood thinners should tell their prescriber before using fenugreek. Case report 50 36 41 16
  • Stomach and gut upset is the most common side effect. Wind, diarrhoea and nausea are the most common effects. The EU monograph lists flatulence, diarrhoea and dizziness with frequency not known, and reports that 25 to 100 g a day of seed powder caused minor stomach and gut symptoms in 4 of 10 cases. A scoping review of 60 articles found mild gut upset the most common effect and attributed no deaths to fenugreek. Authoritative guidance 95 7 31 46
  • Breastfeeding and babies. Fenugreek is a common milk-booster, but LactMed says limited safety data exist for mothers and infants. In the Cochrane review, side effects reported included urine that smelled of maple syrup and hives in infants. LactMed lists diarrhoea, allergic reactions, asthma worsening and, in single mothers, a fast heart rate, breast congestion and skin necrolysis, and notes a survey where 45% of 85 mothers who used fenugreek reported an adverse reaction. The EU monograph says use in lactation is not recommended and that use under 18 has not been established because of lack of safety data. Talk to a lactation consultant and doctor first; milk supply problems need checking of latch and feeding frequency. Authoritative guidance 95 1 27 12
  • Hormone-active extracts: caution with hormone-sensitive conditions, and with testosterone-booster blends. Some fenugreek extract trials in women found rises in estradiol (+120% in one, +18.9% in another) and in free testosterone. Anyone with a hormone-sensitive cancer or condition should ask an oncologist or doctor first. Two case reports describe lung blood clots (pulmonary embolism) in men taking fenugreek-containing testosterone-booster supplements; the products were mixtures and cause was not proven. Case report 79 44 70 4 62
  • Raw fenugreek sprouts have been linked to an E. coli outbreak. The 2011 German E. coli O104:H4 outbreak was traced to sprouts from one farm, and trace-back pointed to a lot of fenugreek seeds imported from Egypt as the most likely source of contamination, though the outbreak strain was not found on seeds in the main epidemiology paper. Seeds used for sprouting can carry harmful germs. Pregnant women, young children, older adults and people with weak immunity should avoid raw sprouts. Other 91 14

Systematic review 27
Liver

We found one published case of liver injury with a fenugreek supplement: a woman with breast cancer on ribociclib (a drug known to affect the liver) had grade III liver injury; the fenugreek supplement was found later, and liver tests normalised within eight weeks of stopping ribociclib and four weeks after stopping fenugreek. The authors scored the link as possible to probable, and fenugreek was not the only suspect. LactMed says liver toxicity has been reported with fenugreek alone and in herbal mixtures (its cited reports were not read). Reviews of trials report no liver or kidney toxicity in the trials pooled, and trials of fatty liver and diabetes monitored liver tests without liver harm in the abstracts. LiverTox could not be opened, so its rating is not stated here. 2 1 31 46 10 33 59

How often. No frequency of human liver injury was found.

Monitoring. No official monitoring advice was found. Stop and seek care for yellow skin or eyes, dark urine or pain in the upper right belly. People on liver-affecting drugs should tell their prescriber.

  • . 47-year-old woman with metastatic breast cancer on ribociclib; grade III liver injury; fenugreek-based supplement also taken; RUCAM 4 after revision, Naranjo 4, DIPS 5 (probable herb-drug interaction); normal liver tests after stopping; moved to a different drug without recurrence.

This is a safety connection. It is not evidence that Fenugreek supports liver health.

Medicines and supplements 5
WithWhy it mattersImportanceEvidenceWhat to do
Diabetes medicines (metformin, sulfonylureas such as glibenclamide, insulin)
prescription
Fenugreek seed products lower blood sugar in trials, so they may add to diabetes medicines.The EU monograph asks that blood sugar control be closely monitored in people treated for diabetes. Trials added fenugreek to metformin or sulfonylurea treatment (204 people; 50 people on drugs; 9 finishers on metformin) and did not report severe low blood sugar in their abstracts, but they were small.Authoritative guidance Low certainty 95 38 33 59 99 1If you take diabetes medicine, do not add fenugreek without your doctor knowing. Check blood sugar more often and learn the signs of low sugar.
Warfarin and other blood thinners
prescription
Unknown. Fenugreek is listed among herbs that may add to blood thinning; the one case involved boldo too.One case: INR rose twice when boldo and fenugreek were taken, and normalised when stopped (Naranjo: probable). A study of 250 people on warfarin found too few fenugreek users to judge. Reviews call the evidence weak.Case report Very low certainty 50 36 41 16 1If you take warfarin, tell your prescriber before using fenugreek, and have the INR checked after starting or stopping.
Ribociclib (a breast cancer drug) and other CYP3A4-processed medicines
prescription
In the lab, high concentrations of a fenugreek extract blocked the liver enzymes CYP2D6 and CYP3A4; in six healthy volunteers taking the powder for a week, enzyme activity did not change significantly.One case report of liver injury with ribociclib and fenugreek (DIPS: probable herb-drug interaction). The six-person study and lab work do not support a large effect.Case report Very low certainty 2 3Cancer patients should not add fenugreek or any supplement without telling their oncology team.

Overdose, product quality and regulators

Summary. Fenugreek is eaten widely as a spice, and doses in the trials read were generally well tolerated. High doses of seed in animals harmed reproduction. The EU monograph says reproductive studies were not adequate and genotoxicity and carcinogenicity tests had not been done.

Animal. EU monograph (preclinical section): lower triiodothyronine (T3) in rodents given hydro-ethanolic extracts at 110 mg/kg a day and above, no safe level (NOAEL) determined; testicular toxicity and lower fertility in mice, rats and rabbits at high doses of seed; embryo resorption, foetal death, growth retardation, malformations and altered neurobehavioural performance in rats and mice at high doses. A toxicology review (Ouzir 2016) reports similar findings and anti-implantation and abortion-causing activity in females, with oxidative stress and DNA damage in the testes of male animals.

Human doses studied. Trials read used from 0.5 to 1 g a day of extracts up to 25 g twice a day of seed powder (in one trial lasting a month); a 3-year trial used 10 g a day. These are not recommendations.

High dose or long term signals. EU monograph: 25 to 100 g a day of seed powder caused minor gut symptoms in 4 of 10 cases. The 3-year trial in prediabetes reported no adverse effects. No long-term safety study of extracts was found.

Overdose response. Gut symptoms (EU monograph). No deaths were attributed to fenugreek in a 2026 scoping review of 60 articles.

Genotoxicity. The EU monograph says tests on genotoxicity and carcinogenicity have not been performed.

Toxic plant parts. No toxic part of the seed was identified in the sources read. The leaf was not covered by a safety source read.

The proven quality problem is germs on seeds used for sprouting. Fenugreek products are also a hidden allergen in spiced foods: in a survey only about one third of fenugreek-containing foods were labelled correctly.

E. coli O104:H4 outbreak in Germany, 2011. Trace-back pointed to sprouts from one German farm and to a lot of fenugreek seeds imported from Egypt as the most likely source of contamination (Weiser 2013). The main epidemiology paper (Buchholz 2011) named sprouts as the likely vehicle and could not identify the outbreak strain on seeds from the implicated lot. 91 14

Allergen labelling. About one third of fenugreek-containing food products were labelled correctly in a survey; the dose of fenugreek powder that caused symptoms in a challenge was about 2 mg. 23

Supplements with undeclared ingredients. The authors of one lung-clot case report comment that supplement ingredients are poorly regulated and occasionally tainted with unlisted ingredients; this is an author comment, not a survey of fenugreek products. 4

Heavy metals, pesticides, mould toxins. No survey of fenugreek products for these was found in the sources read.

When to get medical help
  • Swelling of the face, lips or throat, trouble breathing, wheezing, fainting or widespread hives after fenugreek: call emergency services now (possible anaphylaxis), especially with a peanut or legume allergy.
  • Painful blistering rash, skin peeling or sores in the mouth or eyes: go to emergency care (a severe skin reaction was reported in a new mother).
  • Shaking, sweating, confusion, severe weakness or fainting, especially if you take diabetes medicine: check blood sugar and get urgent help.
  • Black or bloody stools, vomiting blood, nosebleeds that will not stop or unusual bruising while on warfarin: seek urgent care.
  • Sudden chest pain, shortness of breath, coughing blood or one swollen painful leg: go to emergency care (blood clots were reported with testosterone-booster blends).
  • Yellow skin or eyes, dark urine or severe upper-right belly pain: stop and seek care (possible liver injury).
  • A newborn who smells of maple syrup: tell doctors that the mother used fenugreek, but a baby who is feeding poorly, very sleepy or vomiting still needs urgent medical assessment.

Stop the supplement and contact a clinician or emergency service. In the US, Poison Control is 1-800-222-1222.

Frequently asked questions

Does fenugreek lower blood sugar?

Probably a little, in people with type 2 diabetes, but the evidence is weak. Several pooled analyses of small trials found modest falls in fasting sugar and HbA1c, for example about 0.6 to 0.9 points for HbA1c. The trials are mostly low quality and disagree, and one analysis found no clear fall in fasting or after-meal sugar. The US National Center for Complementary and Integrative Health says there is not enough high-quality evidence. It cannot replace diabetes medicine.

61 31 78 45 46 99

Is it safe to take fenugreek with diabetes medicine?

It needs medical supervision. Fenugreek can lower blood sugar, so it may add to metformin, sulfonylureas or insulin. The EU monograph says blood sugar control should be closely monitored in people treated for diabetes, and the NCCIH says large amounts may cause a harmful drop in blood sugar. Tell your doctor, and know the signs of low blood sugar.

95 99 38 33

Does fenugreek boost testosterone?

Maybe slightly, but the evidence is very uncertain. A 2026 review of 13 trials in men found a small rise in total testosterone, no clear rise in free testosterone, no trial at low risk of bias, and certainty rated very low; it says the evidence does not support testosterone-boosting claims. Many trials tested branded extracts and some were sponsored or had no placebo.

92 40 54 51

Does fenugreek increase breast milk?

It is very uncertain. A Cochrane review rated the evidence low to very low for natural milk boosters including fenugreek. Some small trials found more milk, one found a difference at day 7 but not day 15, and a trial of lactation cookies found no effect. A National Library of Medicine database says the effect may be mostly psychological. Talk to a lactation consultant and doctor first; see the safety tab for risks.

27 73 64 1 88

Why does fenugreek make me smell like maple syrup?

Fenugreek can give urine, sweat and skin a maple-syrup smell. It is harmless in itself. One flavour compound, sotolone, is shared by fenugreek and by the urine of patients with maple syrup urine disease, a rare inherited illness of babies, and mothers who took fenugreek in labour had newborns with this smell, which led to a false suspicion of the disease. Tell the medical team if a mother took fenugreek, and always get a baby who is unwell checked.

48 68 56 11

Is fenugreek safe in pregnancy?

It is not recommended in medicinal amounts. The EU monograph does not recommend use in pregnancy or in women who could become pregnant and are not using contraception, because animal studies showed reproductive toxicity. The NCCIH says it is not safe in pregnancy in amounts larger than found in food and links it to birth defects. We found no controlled human trial in pregnancy. Eating fenugreek as a spice in food is different.

95 99 63

Is fenugreek safe while breastfeeding, and for babies?

Safety data are limited. The EU monograph does not recommend use during breastfeeding or under age 18. A national drug database notes limited data and lists gut upset, allergy, asthma worsening and the maple-syrup odour of urine, sweat and possibly breast milk. The Cochrane review reported hives in infants and maple-syrup urine odour as the minor effects. One new mother developed a severe blistering skin reaction. Ask a doctor first.

95 1 27 12

Can people with peanut allergy take fenugreek?

They should avoid it. Fenugreek is a legume, its proteins resemble major peanut allergens, and in one study most blood samples from peanut-allergic patients also reacted to fenugreek. About 2 mg of powder caused symptoms in one challenge. The EU lists allergy to peanut, soya and other legumes as a contraindication. Reactions include wheezing, facial swelling and anaphylaxis.

95 23 24 65 42 17

Does fenugreek interact with blood thinners?

Possibly. One woman on warfarin had a rise in her INR (blood-thinning test) when she took products with boldo and fenugreek; it fell when she stopped and rose again when she restarted. Reviews list fenugreek as a possible interaction, but nearly all the evidence is single cases. Tell your prescriber and ask about INR checks.

50 36 41

Does fenugreek help period pain or menopause symptoms?

Possibly a little, but the evidence is low quality. A 2024 analysis of four trials found less period pain than placebo and the same as a standard painkiller, but rated the effect highly uncertain. Three small trials of branded extracts reported fewer hot flushes and night sweats in women around menopause, and two found rises in estradiol; women with hormone-sensitive conditions should ask a doctor first.

34 93 84 79 44

Does fenugreek lower cholesterol or help with weight loss?

It may lower cholesterol slightly, but it does not help weight loss. Pooled trials found total cholesterol about 9 mg/dL lower and small falls in triglycerides, with disagreement on LDL, and no change in body weight or BMI. No trial looked at heart attacks.

8 37 45 25

What side effects does fenugreek have, and when should I get help?

The most common are wind, diarrhoea and nausea; dizziness is also listed. Rarer problems include allergy, low blood sugar and, in single cases, a severe skin reaction and liver injury with a cancer drug. Get urgent help for swelling of the face or throat, trouble breathing, a blistering rash, shaking, sweating and confusion with diabetes medicine, or yellow skin or eyes. Raw fenugreek sprouts have been linked to an E. coli outbreak, so avoid them if pregnant, elderly, a young child or immune-weakened.

How we research
We searched PubMed, read the full text of the EU draft herbal monograph on fenugreek seed (revision 1, March 2021) and the US National Center for Complementary and Integrative Health page, read the LactMed entry through its PubMed record, and checked plant names in GBIF and the NCBI taxonomy and compounds in PubChem. Only abstracts were read for almost all studies. Some sources were not verified: LiverTox (it could not be opened), the final adopted EU monograph (the draft was read), the German Commission E monograph, and the WHO and FDA statements. Certainty ratings are the compiler's own reading, except where the reviewers gave their own (the 2026 testosterone review rates its evidence very low by GRADE; the 2024 dysmenorrhea review rates it low by GRADE). No study is cited that we could not verify.

Where to buy

Check the label first. Whatever you buy, look for these:

  • The plant part and the extract type or ratio on the label
  • A standardized amount of the active compounds, where relevant
  • A third-party testing mark (USP, NSF or ConsumerLab)
  • Interactions: ask a pharmacist if you take medicines, are pregnant or have a medical condition

Talk to a pharmacist or doctor before you start any supplement, especially if you take medicines. See the Safety tab for interactions.
