Blood Sugar Imbalance

Nutrients connected to Blood Sugar Imbalance

A link means the body needs the nutrient for this, or that low intake is linked to it. It does not mean extra supplements help if your intake is already adequate; each link shows how strong the evidence is.

CinnamonPreliminary or mixed
Cinnamon supplements lowered blood sugar markers in trials of adults with type 2 diabetes; evidence is mixed.
FenugreekPreliminary or mixed
Studied in people with type 2 diabetes and prediabetes, with lower glucose markers in small trials; not a replacement for treatment.
Bitter MelonPreliminary or mixed
Studied in adults with type 2 diabetes with mixed results; it is not a substitute for medical care.
Black seedPreliminary or mixed
Pooled trials in people with metabolic disease found lower fasting glucose and HbA1c, but study quality varied and the authors urge caution. Not a replacement for diabetes care.
BarberryPreliminary or mixed
Small trials suggest it may lower glucose markers in type 2 diabetes, but evidence is limited and mixed.
GymnemaPreliminary or mixed
Studied in people with type 2 diabetes with lower glucose than at baseline in small studies; it is not a substitute for medical care.
BerberinePreliminary or mixed
Used to lower raised blood sugar in type 2 diabetes in trials, with small average effects.

Studied for raised blood sugar; evidence is limited and reviews say it is not enough to call it effective.
CinnamonPreliminary or mixed
Studied as an add-on in type 2 diabetes with mixed results.
CuminPreliminary or mixed
Pooled trials of cumin supplements disagree on blood sugar; evidence is for supplements, not food amounts.

Coriander seedPreliminary or mixed
A small trial in type 2 diabetes reported better glucose markers with seed powder.

In a 2014 outbreak in India, lychee eating, especially without an evening meal, was linked to low blood sugar and brain illness in children.
OkraPreliminary or mixed
Pooled small trials of okra products found lower fasting glucose or HbA1c in people with type 2 diabetes or prediabetes; certainty is low to very low and it is not a replacement for treatment.
Nopales (Prickly Pear Pads)Preliminary or mixed
Studied for after-meal blood sugar in type 2 diabetes in small studies; not a treatment.
Dried fenugreek leaf (kasuri methi)Preliminary or mixed
Studied in people with type 2 diabetes and prediabetes; lower glucose markers in small trials; not a replacement for treatment. Based on seed studies, not dried leaf.

The tea-product trials were done in people with raised blood sugar; results are small and preliminary.
QuinoaPreliminary or mixed
Better glucose measures in trials, including people with impaired glucose tolerance.
BuckwheatPreliminary or mixed
Lower glucose in a pooled analysis.
MilletPreliminary or mixed
Lower glucose and HbA1c in a pooled analysis.
SorghumPreliminary or mixed
Lower glucose and HbA1c in a pooled analysis.
Whole-Wheat BreadPreliminary or mixed
Glucose tolerance improved with whole-wheat bread in adults with prediabetes in one crossover trial.
Soda & Diet SodaPreliminary or mixed
Sugar-sweetened soda delivers a large dose of sugar in a drink; cohort studies link it with type 2 diabetes.
ChyawanprashDocumented risk
Sugar and honey content; generally considered contraindicated in diabetes.
HoneyDocumented risk
Honey is a free sugar. An umbrella review advised caution with long-term or high-dose honey in people with health concerns.
ChromiumPreliminary or mixed
Low chromium has been reported in impaired glucose tolerance, but whether supplements correct blood sugar problems is unclear because trials disagree.
Alpha-lipoic acidPreliminary or mixed
Studied in people with type 2 diabetes; effects on blood sugar markers were small and reviews disagree.
Milk ThistlePreliminary or mixed
A small number of human studies, mostly from Middle Eastern countries, suggest milk thistle extracts may help control blood sugar in type 2 diabetes. It is unclear whether results apply elsewhere.
GarlicPreliminary or mixed
NCCIH says supplements may modestly lower blood sugar in people with diabetes.
BilberryPreliminary or mixed
Early trial evidence of a small HbA1c effect; not a substitute for diabetes care.
SchisandraPreliminary or mixed
One trial of a schisandra-soybean mixture lowered glucose markers in adults with mildly raised glucose; schisandra alone is unproven.
American ginsengPreliminary or mixed
Studied as an add-on in type 2 diabetes with modest glucose changes in one small trial. This is not a substitute for medical treatment.
Maqui berryPreliminary or mixed
Maqui lowered after-meal blood sugar in short studies, but long-term benefit is unclear.
Holy basil (tulsi)Preliminary or mixed
One small trial reported lower glucose in type 2 diabetes.
PsylliumPreliminary or mixed
Pooled trials show better fasting glucose in type 2 diabetes; evidence is limited.
MoringaPreliminary or mixed
Used traditionally for blood sugar. One small trial of leaf capsules found lower glucose and HbA1c in prediabetes, but pooled analyses are mixed and the 2025 one found no significant effect.
Black seed (nigella)Preliminary or mixed
Supplement trials in adults with metabolic disease found lower glucose and HbA1c on average.
Dill seedPreliminary or mixed
Insulin resistance markers lowered in small supplement trials.
SpirulinaPreliminary or mixed
Mixed trial results for glucose control in type 2 diabetes.
YaconPreliminary or mixed
Trials looked at insulin resistance and post-meal glucose with mixed results; not shown to treat diabetes.
Bitter leafPreliminary or mixed
Animal studies report glucose lowering; in a small human test a single leaf decoction did not significantly lower blood sugar. No long-term human trial was found.
PomegranatePreliminary or mixed
A 2024 meta-analysis found small reductions in fasting glucose and HbA1c; NCCIH calls the reduction small. Not a treatment for diabetes.
SalaciaPreliminary or mixed
Used for raised blood sugar; evidence is small-trial level.
Jamun (Java plum seed)Preliminary or mixed
Used for raised blood sugar; evidence is limited and low certainty.
Indian bay leaf (tej patta)Lab or animal research only
Only animal findings of lower glucose; nothing in people.
PotatoesPreliminary or mixed
Frequent french fries were linked with higher type 2 diabetes risk in cohorts; baked, boiled or mashed potatoes were not clearly linked. Observational only.
Cinnamon TeaPreliminary or mixed
Same evidence as above.
LentilsPreliminary or mixed
Pooled trials of pulses as a group found lower fasting glucose and insulin, with large differences between trials. In an 8-week lentil trial insulin resistance rose in the control group and fell with lentils; in a 12-week trial fasting glucose and HbA1c did not differ.
Chickpeas (Garbanzo Beans)Preliminary or mixed

Pooled trials of pulses as a group found lower fasting glucose and insulin, with large differences between trials. Bread with split pea flour did not significantly change glucose or insulin in 24 healthy adults.
Black-Eyed Peas (Cowpeas)Preliminary or mixed
Pooled trials of pulses as a group found lower fasting glucose and insulin, with large differences between trials. In one small trial of 11 healthy adults, cowpea varieties gave a lower blood sugar response than glucose.
