White tea: the pale brewed drink and the dried buds and young leaves.

White Tea

Q: What is white tea?

White tea is a drink made from the tender buds and young leaves of the tea plant, Camellia sinensis, with very little processing. It is the same plant as green, black and oolong tea. It contains caffeine and catechins.

Q: How is white tea different from green tea?

White tea is the least processed tea. In one lab study of tea from the Azores, green tea had more catechins and phenolics than white tea, while white tea had more caffeine per gram of dry leaf. A review calls white tea a variety of green tea. No source read shows that the differences matter for health.

Q: Does white tea have less caffeine than other teas?

Not reliably. One US lab found 14 to 61 mg per serving across white, green and black teas with no trend by variety. A 2025 lab measured about 5.8 mg per 200 mL for white tea, lower than black or green. The Azorean lab found more per gram of dry leaf in white tea than in green. Amounts depend on the leaf and steeping.

Q: Does white tea help with weight loss?

This has not been shown. A pilot study found a short rise in resting energy use in 32 women. In a 12-week study in people with obesity, weight fell in every group, including the control group.

Q: Does white tea help with blood sugar or diabetes?

One small 6-month trial of 49 women reported lower glucose and insulin, but gave no numbers and has a registry number that looks like a placeholder. The evidence is insufficient. Talk to your doctor before changing diabetes care.

Q: Does white tea lower cholesterol or help the heart?

Two small studies report lower LDL cholesterol, but neither is a placebo-controlled trial. Liver cell experiments show changes in fat-handling genes, which is not proof for people. No white tea study looked at heart attacks or strokes.

Q: Is white tea full of antioxidants, and does that matter?

Lab tests show antioxidant activity in white tea, and a review says it may be higher than in green tea. Test-tube activity does not show a benefit in people, and the reviewer called white tea data very limited.

Q: Is white tea safe in pregnancy, breastfeeding or for children?

It contains caffeine, which counts toward your daily limit. The NHS says not more than 200 mg a day in pregnancy. NCCIH says caffeine passes into breast milk, and low-to-moderate intake usually has no effect on the baby. The FDA says to avoid caffeinated drinks for children under 2. No source read covers white tea extracts, so ask a clinician.

Q: Can white tea hurt the liver, and what about extracts?

No liver injury linked to white tea was found in the sources read. Rare liver injury has been reported for green tea extracts, and EFSA found liver enzyme rises with high-dose catechin supplements. White tea extracts have not been assessed, so do not assume they are the same or different. Stop any extract and get care if you have yellow skin or eyes or dark urine.

Camellia sinensis · also called White tea, tea (minimally processed bud and leaf tea). Not the same as white tea extracts or mouthwashes.

White tea is a drink made from the buds and young leaves of the tea plant, with very little processing. People drink it for general wellbeing, weight and blood sugar. Only a few small human studies exist, and they are not strong enough to show that white tea helps. The main known effect is caffeine, and measured amounts differ between labs.

About White Tea

White tea is the drink from the buds and young leaves of the tea plant with minimal processing. Human research is thin: three small studies, none strong. No white tea safety studies were found. Caffeine is the main known concern, and published caffeine values differ. Extract capsules and mouthwashes are separate products and are not judged by tea results.

What it is

White tea comes from Camellia sinensis, a plant of the tea family (Theaceae) that GBIF accepts as a species. It is the same plant as green, black and oolong tea. White tea uses tender buds and young leaves with minimal processing. One review calls it a variety of green tea, and a chemistry study calls it the least processed form of tea.

The drink contains caffeine, catechins such as EGCG, and L-theanine. Lab studies found differences from green and black tea made from the same leaves, but no source read shows that those differences matter for health.

^{25 15 1 5 22 23 24}

Tea, extract or mouthwash?

A cup of white tea is a weak water extract of the buds and leaves. White tea extracts and mouthwashes are different products, and most cell and animal studies use extracts. The human studies read used the drink. For green tea, EFSA found liver enzyme rises only with high-dose supplements, and no source read covers white tea extracts. Do not carry results from one form to another.

^{7 11 15}

What the research shows

A pilot study in 32 healthy women found resting energy use rose 8.7% three hours after white tea, with no comparison drink described. In people with obesity, weight fell in all groups over 12 weeks, including controls. A 6-month trial in 49 women with type 2 diabetes reported better glucose and blood fats, but gave no numbers and has an unconfirmed registry number.

Cell experiments show white tea extract changes fat-handling genes in liver cells. This does not show the same in people. A 38-study analysis links tea drinking with lower death rates, but it is tea in general and cannot show cause. A 2015 overview said very few white tea data existed.

^{15 2 6 11 10 16}

Caffeine, fluoride and what is in the leaf

Fluoride: a review of 88 studies found average fluoride was 0.49 mg/L in white tea, lower than green (1.37) and black (2.73). Fluoride builds up in mature leaves more than in buds, and longer brewing releases more. Fluoride matters most for young children and very heavy tea drinkers.

Pesticides: one two-year survey in Fujian, China found 25 pesticides and at least one residue in 74.8% of white tea samples. Risk to consumers was judged extremely low, but it is one region. No lead, cadmium or aluminium values for white tea were found in the sources read, so these are unknown.

^{9 12 17}

Regulators and status

No regulator page or herbal monograph for white tea was read. NCCIH, the FDA and the NHS give caffeine and green tea guidance, and EFSA has an opinion on green tea catechins. The EMA, LiverTox and LactMed were not looked up for white tea.

Isolated compounds versus whole extracts

Brewed white tea, tea bags, ready-to-drink bottles and white tea extracts or mouthwashes are different products. The human studies read used brewed tea. Cell and animal studies mostly use extracts. Safety information on concentrated catechin supplements comes from green tea and should not be carried over to the drink, or to white tea extracts.

Nutritional composition

White tea is not a source of essential nutrients in the sources read. It contains caffeine, catechins, amino acids and other compounds, and tea can lower iron absorption from a meal (other teas tested).

Energy use at rest

Very low certainty

One small pilot study in 32 healthy women found that resting energy use rose about 9% three hours after drinking white tea. It was a single session with no comparison drink described, so it is not known whether the tea, its caffeine or the passing of time caused the rise.

1 studiesBrewed white tea in a single session. Amount not stated here.

Studies, doses and limits

What the trials found

One pilot study (Tek 2024) of 32 healthy women with normal blood pressure. They had baseline measurements, then drank white tea measured out by its caffeine content, and were tested at 30, 120 and 180 minutes. Resting energy use rose 8.7% at 180 minutes (p < 0.05). Oxygen use and body temperature also rose. Blood pressure and heart rate did not change. No comparison drink is described in the abstract.

Results

Resting energy use +8.7% at 180 minutes (p < 0.05); blood pressure and heart rate unchanged.

Effect sizes as reported

About 9% rise in resting energy use for a few hours in one group of women.

Why this rating

One small pilot with no comparison drink described, one session only, healthy women only, and the tea was dosed by caffeine so caffeine cannot be ruled out.

Form and dose studied

Brewed white tea in a single session. Amount not stated here.

Who was studied

Healthy women with normal blood pressure.

Limits

No comparison drink; very short follow-up; no evidence that a short rise changes body weight.

Why researchers looked

White tea is made from buds and young leaves with little processing, and some authors suggest this leaves more bioactive compounds that could raise heat production.

Traditional use

Not described in the sources read.

Proposed mechanism Hypothesis

Hypothesis by the study authors that minimal processing leaves more compounds that raise heat production. Not tested in the study.

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

White tea contains caffeine, and there are no white tea safety trials. See the Safety tab for caffeine, pregnancy, iron and medicine cautions.

Body weight and waist size in obesity

Very low certainty

A 12-week study in people with obesity found that weight, waist size and BMI fell in every group, including the group given only a diet and exercise program. So it does not show that white tea caused weight loss.

Studies, doses and limits

What the trials found

In the 12-week study (Akyildiz 2024), people with obesity were put into four groups: control, orlistat, metformin or white tea. All groups got a diet and exercise program. Body weight, waist and BMI fell significantly in all groups. The abstract does not say whether the white tea group lost more than the control group. A 2015 overview said very few human data about white tea exist.

Results

Weight, waist circumference and BMI fell significantly in all four groups; no between-group difference is given in the abstract.

Effect sizes as reported

Not given for white tea versus control.

Why this rating

Weight fell in the control group too, the abstract gives no number of people, no amount of tea and no between-group comparison.

Form and dose studied

White tea compared with control, orlistat and metformin. Amount not stated in the abstract.

Who was studied

People with obesity; sex, age and numbers not given in the abstract.

Limits

Control group also lost weight, so the tea's own effect is unknown; short; no long-term follow-up.

Why researchers looked

People with obesity look for easy additions to diet and exercise, and green tea has been studied for weight, so white tea has been tried too.

Studies, doses and limits

What the trials found

A randomised trial (Dardashti Pour 2021): 49 women with type 2 diabetes were assigned to control, white tea, aerobic training, or training plus white tea for six months. Glucose, insulin, LDL, cholesterol and triglycerides fell and HDL rose in treated groups compared with before the trial or with the diabetic control group. The authors say white tea plus training improved blood sugar, blood fats, blood pressure and peak oxygen use.

Results

Significant improvements reported; sizes not given in the abstract.

Effect sizes as reported

Not given in the abstract.

Why this rating

Small, no numbers or tea amount in the abstract, effects of exercise not separated from tea in the conclusion, and a registry number that looks like a placeholder.

Form and dose studied

White tea alone or with aerobic training. Amount not stated in the abstract.

Who was studied

49 women with type 2 diabetes.

Limits

Women only; the abstract does not separate the white-tea-only group from the exercise groups; no HbA1c result reported.

Why researchers looked

Plant compounds called flavonols in tea have been proposed to help control blood sugar.

Studies, doses and limits

What the trials found

In the 12-week study (Akyildiz 2024), the white tea group had significant falls in TNF-alpha, IL-6, IL-1 beta, MMP-9, total cholesterol, LDL cholesterol and triglycerides, a rise in HDL cholesterol, and falls in leptin, ghrelin and asprosin (hunger and fat hormones). Markers of oxidative stress (MDA and 8-OHdG) fell and glutathione (GSH) rose. Glucose fell in all groups except the control.

Results

Significant changes in the white tea group; no numbers or between-group comparison in the abstract.

Effect sizes as reported

Not given.

Why this rating

Before-and-after changes in one group of a small, short study; no between-group comparison; diet and exercise program was given to everyone.

Form and dose studied

White tea alongside diet and exercise, compared with control, orlistat and metformin.

Who was studied

People with obesity.

Limits

The abstract does not tell us if the changes were larger than in the control group; sizes not given.

Why researchers looked

Obesity raises blood fats and inflammation, and tea compounds are thought to act as antioxidants.

Traditional use

Not described in the sources read.

Death rates in people who drink tea (tea in general)

Not enough evidence

A pooled analysis of 38 population studies found that people who drank the most tea had about 10% lower risk of dying from any cause than people who drank the least. This is tea in general: the abstract does not say how much of it was white tea, and it cannot show cause and effect.

1 studiesTea in general; types not separated in the abstract.

Studies, doses and limits

What the trials found

A meta-analysis (Kim 2024) of 38 prospective cohort data sets (1,956,549 people): highest versus lowest tea drinking gave a risk ratio of 0.90 for death from any cause, 0.86 for heart disease death and 0.90 (not statistically significant) for cancer death. The best results were at about 2 cups a day for all-cause death, with no extra benefit beyond that.

Results

All-cause 0.90 (95% CI 0.86 to 0.95); cardiovascular 0.86 (0.79 to 0.94); cancer 0.90 (0.78 to 1.03).

Effect sizes as reported

About 10% lower risk of death from any cause, in people who drink tea in general.

Why this rating

For white tea specifically the evidence is insufficient: the abstract does not separate tea types, and population studies cannot show cause.

Form and dose studied

Tea in general; types not separated in the abstract.

Who was studied

Adults in 27 papers; countries not given in the abstract.

Limits

Observational; people who drink tea may differ in other habits; nothing is specific to white tea.

Why researchers looked

Tea drinking is common and large population studies track who lives longer.

Traditional use

Not described in the sources read.

Proposed mechanism Not established

No mechanism was established in the sources read.

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

White tea contains caffeine, and there are no white tea safety trials. See the Safety tab for caffeine, pregnancy, iron and medicine cautions.

Cholesterol handling (cell experiments only)

Not enough evidence

White tea extract changed how liver cells in a dish handle fats and LDL cholesterol. This is a cell experiment and does not show that drinking white tea lowers cholesterol.

1 studiesWhite tea extract on HepG2 cells.

Studies, doses and limits

What the trials found

No human evidence. The study (Luo 2020) used white tea extract on cells in a dish.

Results

Cell result only; no numbers in the abstract.

Effect sizes as reported

None in people.

Why this rating

Cell experiment only; extract, not a drink; human liver cancer cell line.

Form and dose studied

White tea extract on HepG2 cells.

Who was studied

Not applicable (cells).

Limits

Does not show the same happens in the body.

Why researchers looked

Researchers wanted to see how white tea extract affects the genes liver cells use to handle fat.

Traditional use

Not described in the sources read.

Proposed mechanism Laboratory research

In HepG2 cells, white tea extract lowered genes for VLDL production and raised LDL receptor activity, with the catechins EGCG and ECG contributing. Cell-level only.

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

White tea contains caffeine, and there are no white tea safety trials. See the Safety tab for caffeine, pregnancy, iron and medicine cautions.

The evidence

The research centre for White Tea. Every record here was checked against PubMed or the publisher's page; we never list a study we have not verified.

Evidence by outcome

Energy use at rest 1 studies Very low certainty Body weight and waist size in obesity 2 studies Very low certainty Blood sugar in type 2 diabetes 1 studies Not enough evidence Blood fats, inflammation and hormone markers in obesity 1 studies Very low certainty Death rates in people who drink tea (tea in general) 1 studies Not enough evidence Cholesterol handling (cell experiments only) 1 studies Not enough evidence

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 and read the abstracts of about 17 papers, read the NCCIH, FDA and NHS pages, checked the plant name in GBIF and three compounds in PubChem. The IARC press release could not be re-read as text, so that line is marked unverified. Only abstracts were read for papers. Certainty ratings are the compiler's own reading. Funding was not stated for most abstracts, so industry links are not ruled out. No study is cited that we could not verify.

What we do not know yet

What the evidence supports: a few small, uncontrolled or poorly described studies of energy use, weight and blood sugar; nothing strong.
No placebo-controlled trial of white tea for any health outcome was found.
Death-rate data are for tea in general, not white tea.
No white tea safety, liver, allergy or interaction study was found.
No lead, cadmium or aluminium values for white tea were read; caffeine values conflict between labs.
The EMA, LiverTox, LactMed and the EFSA caffeine opinion were not opened for white tea.

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".

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 3

Caffeine is the main known effect, and white tea is not reliably low in it. White tea comes from the tea plant, so it contains caffeine. Measured amounts differ between labs: one US lab study found 14 to 61 mg per serving across white, green and black teas with no trend by variety, a 2025 lab study measured about 5.8 mg per 200 mL for white tea (lower than black, yellow and green), and an Azorean study found more caffeine per gram of dry leaf in white tea than in green tea. So claims that white tea has 'little caffeine' or 'more caffeine' cannot be relied on. The FDA says 400 mg a day from all sources is not generally linked with harm in most adults, and the NHS says not more than 200 mg a day in pregnancy. Food analysis and authoritative guidance ^{4 3 13 19 21}
No safety trials or reports for white tea itself were found. The three small human studies of white tea (2021 and 2024) did not report side effects in their abstracts. No case reports of liver injury, allergy or drug interactions with white tea were found in the sources read. That is a gap, not proof of safety. Gap ^{15 2 6}
A cup of tea is not a concentrated extract. The rare liver injury reports for tea products are about green tea extract capsules and tablets. EFSA judged green tea infusions generally safe at European intakes and found liver enzyme rises with high-dose catechin supplements. White tea also contains catechins, but no source read covers white tea extract, and results should not be carried across. Regulator opinion ^{7 20}

Possible harm from very hot drinks to the gullet (oesophagus) IARC says it is the temperature, not the tea, that appears responsible. Limited evidence.	Not stated	serious if it occurs Not stated	Authoritative guidance ¹⁸
Nausea, constipation, stomach discomfort and higher blood pressure (extract supplements) NCCIH lists these for green tea extract. This comes from green tea; no white tea study was found.	No rate in the source read	mild Not stated	Authoritative guidance ²⁰

Liver

No liver injury linked to white tea was found in the sources read. For green tea, EFSA found that high-dose catechin supplements raised liver enzymes in trials and that rare liver injury has been reported after infusions, most probably an individual reaction. NCCIH says liver injury is uncommon and mostly tied to extract capsules or tablets. White tea contains catechins too, but how white tea or its extracts behave in the liver has not been studied in the sources read. ^{7 20}

How often. No rate for white tea could be found.

Monitoring. No agency monitoring advice for white tea was read. People who have had liver problems from a supplement should ask a clinician before using any tea extract.

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

Medicines and supplements 5

With	Why it matters	Importance	Evidence	What to do
Warfarin (blood thinner) prescription	The case authors suggested vitamin K in green tea could work against warfarin. Vitamin K in white tea was not measured in any source read.	One 1999 case report on green tea: the INR fell from 3.79 to 1.37 about a week after the man began drinking very large amounts of green tea daily, and rose to 2.55 after he stopped. Nothing was found about white tea.	Case report (green tea) Very low certainty ¹⁴	If you take warfarin, tell your prescriber about any big change in how much tea you drink so your INR can be checked.
Nadolol (beta-blocker), atorvastatin (cholesterol medicine) and raloxifene (bone medicine) prescription	Not described in the source read.	NCCIH says high doses of green tea reduced blood levels of nadolol, green tea extract reduced blood levels of atorvastatin, and a study showed an interaction with raloxifene. None of this was tested with white tea.	Authoritative guidance (green tea) Very low certainty ²⁰	Ask your pharmacist before taking tea extracts with these medicines.
Iron from food and iron supplements nutrient	Tea polyphenols reduced absorption of non-haem iron from a meal in a dose-related way in a radio-iron study of black tea and herb teas. White tea was not tested.	Black tea cut iron absorption by 79 to 94% in that study. Whether white tea does the same is unknown.	Human study (other teas) Low certainty ⁸	If your iron is low, ask a clinician about when to drink tea.
Other sources of caffeine (coffee, cola, energy drinks, supplements) stimulant	Caffeine from all sources adds up.	The FDA counts caffeine from all sources toward the daily amount.	Authoritative guidance Moderate certainty ¹⁹	Count white tea with your other caffeine.
No white tea drug interaction study found gap	n/a	No interaction study of white tea with any medicine was found. The entries above come from green tea or other teas.	Gap Not enough evidence	If you take any medicine, ask your pharmacist.

Who should check first 6

Situation	Advice	Evidence
Pregnancy	White tea is not named as banned, but it contains caffeine and counts toward the daily limit. The NHS says not more than 200 mg of caffeine a day in pregnancy and links too much caffeine to a higher chance of miscarriage and stillbirth. A review of white and green tea suggests cutting down tea in the last trimester, though the evidence behind that line was not read. No source read covers white tea extract in pregnancy, so ask a clinician.	Authoritative guidance ^{21 1 20}
Breastfeeding	NCCIH says caffeine passes into breast milk; high intake can cause fussiness and poor sleep in the baby, but low-to-moderate intake usually has no effect. No studies of white tea extract in breastfeeding were found.	Authoritative guidance ²⁰
Infants and young children	The FDA, quoting the Dietary Guidelines, says caffeinated drinks should be avoided for children under 2. Tea can also lower iron absorption. Fluoride in tea matters most for young children.	Authoritative guidance ^{19 9 8}
Low iron or anemia	Ask a clinician. Tea drinks lowered iron absorption in a study of other teas.	Human study ⁸
Heart rhythm problems, anxiety, trouble sleeping or high blood pressure	The FDA lists a fast heart rate, high blood pressure, anxiety, jitters and insomnia among signs of too much caffeine. Ask a clinician how much caffeine suits you.	Authoritative guidance ¹⁹
Taking warfarin, nadolol, atorvastatin or raloxifene	Ask your pharmacist or prescriber before changing how much tea or extract you take.	Case report and authoritative guidance (green tea) ^{14 20}

Overdose, product quality and regulators

Summary. No toxicity study of white tea in people was found. The best-known concerns for tea are caffeine and, for concentrated green tea extracts, the liver.

Animal. Rat and cell studies of white tea exist but were not read for safety.

Human doses studied. The three small white tea human studies did not report side effects in their abstracts. The FDA says toxic effects such as seizures can occur with rapid intake of around 1,200 mg of pure caffeine; this is about concentrated caffeine products, not tea.

High dose or long term signals. Not studied for white tea.

Overdose response. Not described for white tea.

Genotoxicity. Not read.

Toxic or hazardous parts. Buds and young leaves are used. No source read compared parts.

Measured contaminant data for white tea are thin. One survey found pesticide residues. Fluoride is lower in white tea than in green or black tea on average. No lead, cadmium or aluminium values for white tea were found in the sources read. That means unknown, not shown safe.

Pesticide residues. A two-year survey of white tea in Fujian, China found 25 pesticides, and 74.8% of samples had at least one residue. Bifenthrin was most common (61.6%). Dietary risk was judged extremely low for six groups of residents, with isocarbophos and triazophos ranked medium risk. One region; not a brand. ¹⁷

Fluoride. A scoping review of 88 studies gave average fluoride of 0.49 mg/L in white tea, against 1.37 for green, 2.73 for black and 4.78 for brick tea. Fluoride built up most in mature leaves, then stems and buds, and longer brewing released more. A Polish study of 98 leaf teas (7 white) found fluoride risk scores below the threshold for all, with the highest in elderly low-weight people drinking green tea. ^{9 12}

Heavy metals. Not found for white tea in the sources read.

Supplements and extracts. White tea extracts and mouthwashes exist. No quality testing of them was found in the sources read. The FDA does not approve dietary supplements before sale (NCCIH). ²⁰

Body	Action	Date
NCCIH (NIH) (United States)	No page for white tea. The green tea page says no safety concerns have been reported for green tea as a beverage in adults, lists extract side effects, rare liver injury, medicine interactions and a caffeine caution in pregnancy. source	2025-02
FDA (United States)	Cites 400 mg of caffeine a day as an amount not generally linked with negative effects in most adults; lists green tea at 37 mg per 12 fl oz; advises avoiding caffeinated drinks for children under 2; says pregnant or breastfeeding people should talk to a health professional. White tea is not listed. source	2024-08-28
NHS (United Kingdom)	Says not more than 200 mg of caffeine a day in pregnancy and gives about 75 mg for a cup of black or green tea; links too much caffeine to a higher chance of miscarriage and stillbirth. source	2026-06-15
EFSA (European Union)	Opinion on green tea catechins: traditional green tea infusions generally safe at EU intakes; rare liver injury after infusions; high-dose EGCG supplements raised liver enzymes in trials. Does not cover white tea. source	2018

When to get medical help

Chest pain, a racing or irregular heartbeat or fainting: call emergency services.
Yellow skin or eyes, dark urine, pale stools, strong tiredness or pain in the upper right belly while using a tea extract: stop it and get medical care now.
Black stools, unusual bruising or bleeding if you take warfarin: contact your prescriber or emergency services.
Very pale skin, breathlessness or marked tiredness in someone with low iron who drinks a lot of tea: see a clinician.

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

General information only, not medical advice. Ask a clinician or pharmacist before use, especially with medicines, in pregnancy or with a health condition. See the Natural Remedy Safety guide.

Frequently asked questions

What is white tea?

White tea is a drink made from the tender buds and young leaves of the tea plant, Camellia sinensis, with very little processing. It is the same plant as green, black and oolong tea. It contains caffeine and catechins.

^{15 25 5}

How is white tea different from green tea?

White tea is the least processed tea. In one lab study of tea from the Azores, green tea had more catechins and phenolics than white tea, while white tea had more caffeine per gram of dry leaf. A review calls white tea a variety of green tea. No source read shows that the differences matter for health.

^{13 5 1}

Does white tea have less caffeine than other teas?

Not reliably. One US lab found 14 to 61 mg per serving across white, green and black teas with no trend by variety. A 2025 lab measured about 5.8 mg per 200 mL for white tea, lower than black or green. The Azorean lab found more per gram of dry leaf in white tea than in green. Amounts depend on the leaf and steeping.

^{4 3 13}

Does white tea help with weight loss?

This has not been shown. A pilot study found a short rise in resting energy use in 32 women. In a 12-week study in people with obesity, weight fell in every group, including the control group.

^{15 2}

Does white tea help with blood sugar or diabetes?

One small 6-month trial of 49 women reported lower glucose and insulin, but gave no numbers and has a registry number that looks like a placeholder. The evidence is insufficient. Talk to your doctor before changing diabetes care.

⁶

Does white tea lower cholesterol or help the heart?

Two small studies report lower LDL cholesterol, but neither is a placebo-controlled trial. Liver cell experiments show changes in fat-handling genes, which is not proof for people. No white tea study looked at heart attacks or strokes.

^{2 6 11}

Do people who drink tea live longer?

A pooled analysis of 38 population studies linked the highest tea drinking with about 10% lower all-cause death. It does not separate white tea and cannot show that tea is the cause.

¹⁰

Is white tea full of antioxidants, and does that matter?

Lab tests show antioxidant activity in white tea, and a review says it may be higher than in green tea. Test-tube activity does not show a benefit in people, and the reviewer called white tea data very limited.

^{13 16}

Is white tea safe in pregnancy, breastfeeding or for children?

It contains caffeine, which counts toward your daily limit. The NHS says not more than 200 mg a day in pregnancy. NCCIH says caffeine passes into breast milk, and low-to-moderate intake usually has no effect on the baby. The FDA says to avoid caffeinated drinks for children under 2. No source read covers white tea extracts, so ask a clinician.

^{21 20 19}

Can white tea hurt the liver, and what about extracts?

No liver injury linked to white tea was found in the sources read. Rare liver injury has been reported for green tea extracts, and EFSA found liver enzyme rises with high-dose catechin supplements. White tea extracts have not been assessed, so do not assume they are the same or different. Stop any extract and get care if you have yellow skin or eyes or dark urine.

^{7 20}

Does white tea interact with medicines or iron?

No white tea interaction study was found. For green tea, NCCIH reports lower blood levels of nadolol and atorvastatin, and one case report links very large amounts with weaker warfarin effect. Tea lowered iron absorption in a study of black and herb teas. Ask your pharmacist.

^{20 14 8}

What about fluoride, pesticides and very hot tea?

Average fluoride was lower in white tea (0.49 mg/L) than in green or black tea. A survey in Fujian, China found pesticide residues in 74.8% of white tea samples, with extremely low judged risk. IARC says very hot drinks are probably carcinogenic to the oesophagus because of heat, so let a cup cool.
