What is it

Indian gooseberry (Phyllanthus emblica), also called amla or amalaki, is a small green-yellow fruit from a tree native to India. It is one of the most important fruits in Ayurvedic medicine and is valued for its high vitamin C content and unique tannin compounds called emblicanins.

How it works

Amla's primary bioactive compounds are tannins (emblicanin A and B, punigluconin, pedunculagin) and ascorbic acid. The vitamin C in amla is unusually stable due to the presence of these tannins, which protect ascorbic acid from oxidative degradation. Fresh amla contains roughly 600 to 700 mg of vitamin C per 100 g. The tannins themselves act as antioxidants and have been studied for effects on cholesterol, glucose metabolism, and inflammation. Polyphenols in amla may inhibit cholesterol biosynthesis pathways and modulate gut microbiota in animal and limited human studies. In Ayurvedic tradition, amla is a key ingredient in rasayana preparations (rejuvenating tonics) and chyawanprash. It is often consumed in dried fruit, powder, or extract forms in modern supplement use.

Evidence for 5 uses

AI-assisted evidence assessment — talk to your doctor before relying on any single supplement.

Vitamin C source

Grade B

Good evidence

Amla provides bioavailable vitamin C in a stable form. The presence of tannins helps preserve ascorbic acid during processing and storage compared with many other vitamin C-rich foods.

Cholesterol and lipid profile

Grade C

Moderate evidence

Several small randomized trials and meta-analyses suggest amla extract may reduce total cholesterol, LDL, and triglycerides while increasing HDL modestly. Effects appear over 8 to 12 weeks. Trial quality is moderate and effect sizes vary.

Glycemic control

Grade C

Moderate evidence

Small trials in people with type 2 diabetes suggest amla may modestly improve fasting glucose and HbA1c. Evidence is preliminary and amla should not replace prescribed therapy.

Endothelial function

Grade C

Moderate evidence

A few trials report improved markers of endothelial function and reduced inflammatory markers (hs-CRP) with standardized amla extracts. Sample sizes are small but results are reasonably consistent.

Hair health (topical)

Grade F

Limited evidence

Traditional use of amla oil for hair conditioning and pigmentation is widespread, but rigorous clinical evidence for hair growth or graying is lacking. Mechanistic and small open-label data exist.

4 commercial forms

Amla powder

Traditional whole-fruit form; preserves natural tannins and vitamin C.

Dried and ground fruit pulp. Tart, astringent flavor; often mixed into warm water, juice, or yogurt.

Standardized extract

Concentrated tannins or vitamin C; precise dosing.

Capsules standardized to a specific tannin or polyphenol percentage. Brands like Capros have been used in clinical trials.

Fresh or candied fruit

Full spectrum of natural compounds; vitamin C content highest when fresh.

Traditional consumption form in India. Murabba (a sweet preserve) and pickled amla are common preparations.

Amla juice

Liquid form; some vitamin C may oxidize during processing.

Diluted juice is taken in Ayurvedic practice. Quality and concentration vary widely between brands.

Dosage

There is no RDA. Clinical studies typically use 500 mg to 3 g of amla powder or extract daily, often split into two doses. Fresh fruit consumption of 1 to 2 fruits per day is traditional. Standardized extracts (such as Capros, standardized to low-molecular-weight tannins) have been used at 500 mg twice daily in trials. No formal Upper Limit.

When and how to take it

Amla can be taken at any time of day. Vitamin C and most polyphenols are water-soluble, so fat is not needed. Splitting the dose between morning and evening provides more steady exposure. Some traditional protocols recommend taking amla on an empty stomach in the morning. If taken for blood sugar effects, consume with or just before meals.

Safety

Amla is generally well tolerated at typical supplement doses. Reported side effects include mild gastrointestinal upset, loose stools (due to natural laxative effect of tannins and fiber), and rare allergic reactions. Very high doses may cause stomach acidity in sensitive individuals due to the fruit's sour-acidic taste profile.

Who should be cautious

People scheduled for surgery should stop using amla supplements at least two weeks beforehand. Those on blood thinners, antidiabetic medications, or antihypertensives should consult a clinician. Pregnant and breastfeeding women should avoid concentrated extracts due to limited safety data, though dietary amounts of the fruit are considered acceptable.

Interactions

Amla may have antiplatelet effects and could theoretically increase bleeding risk in people on warfarin, aspirin, or other anticoagulants. It may modestly lower blood glucose and could potentiate antidiabetic medications. Some animal studies suggest amla may affect cytochrome P450 metabolism, with unclear human relevance. The vitamin C content can also enhance non-heme iron absorption.

Frequently asked questions

Is amla the same as Indian gooseberry?⌄

Yes. Amla, amalaki, and Indian gooseberry all refer to the fruit of Phyllanthus emblica. The fruit is unrelated to European or American gooseberries.

How much vitamin C does amla have?⌄

Fresh amla contains roughly 600 to 700 mg of vitamin C per 100 g of fruit. Processed powders retain a portion of this depending on heat and air exposure during manufacture.

Can I take amla every day?⌄

Daily use of 500 mg to 3 g of amla powder has been studied for up to several months and is generally well tolerated. Periodic clinician check-ins are reasonable if used long-term, especially if combined with medications.

Does amla cause loose stools?⌄

Some people experience mild laxative effects, particularly at higher doses. This is attributed to fiber and tannin content and usually resolves with dose adjustment.

What does amla taste like?⌄

Extremely sour, astringent, and slightly bitter. The taste is often masked with honey, salt, or other ingredients.
