in pictures and a few words
What it is and why it matters
Amla is Indian gooseberry. Here it is a herbal supplement: fruit extract in capsules.
- Most studies in people are about blood fats and inflammation
- It is an add-on to lifestyle, not a replacement for treatment
Lower blood fats
Scientists pooled several studies in people. In blood tests, amla lowered one type of cholesterol and other blood fats.
Tested in people. Tested in people: several studies were pooled together.
Fewer signs of inflammation
Blood tests include a marker of inflammation. Amla lowered it, and this is the most robust result: here the studies agreed with each other.
Tested in people. Tested in people: the results of different studies did not diverge.
Fasting blood sugar
Amla lowers fasting blood sugar — this shows when studies are pooled together.
- If you take medicines for blood sugar, read the page “Who should see a doctor first”
Vitamin C: almost six times
Fresh amla has almost six times more vitamin C than an orange. That is a lot — and it is true.
- This is about the fresh fruit, not the capsule
- And “twenty times more” is an old figure copied from book to book
Why an extract
A 10:1 extract is a concentrate: ten parts of fruit give one part of extract. A capsule holds more active compounds than the same weight of dried powder.
How to take it
Take it as the manufacturer directs. A jar holds 50 capsules.
- Don’t convert capsules into grams of fruit from the studies
- Amla does not replace a cholesterol medicine — it adds to it, if your doctor agrees
Amla and blood clotting
Amla affects blood clotting: bleeding takes longer to stop. With blood-thinning medicines, this effect adds up.
- With some of these medicines amla has not been studied at all — that does not mean it is safe
Important. If you take blood-thinning medicines, talk to a doctor before the first capsule, not after.
Who should see a doctor first
There are situations when amla is first discussed with a doctor or not taken at all.
- You take medicines for blood sugar — keep an eye on your blood sugar: together they may lower it more
- Planned surgery — discuss it in advance; amla is usually stopped a few days before
- Pregnancy and breastfeeding — not taken: there are no data
Important. If blood sugar is repeatedly below 3.0 mmol/L (54 mg/dL) or above 8.9 mmol/L (160 mg/dL), see a doctor.
In one sentence
Amla slightly lowers blood fats and the inflammation marker, and the fresh fruit has a lot of vitamin C. But it affects clotting: if you take blood-thinning medicines, see a doctor first.
Key points
Amla, the Indian gooseberry, is a fruit with more evidence than you would expect from a botanical supplement; the table shows what human studies found.
| Where it applies | How it helps | What human studies showed |
|---|---|---|
| Raised LDL-C | lowers LDL-C and VLDL-C | meta-analysis of nine RCTs, 535 participants, 500–1500 mg a day for two to twelve weeks: LDL-C −0.39 mmol/L, CI −0.66 to −0.12 (−15.1 mg/dL, CI −25.4 to −4.7; p = 0.004), VLDL-C −0.14 mmol/L (−5.4 mg/dL; p = 0.0003) versus placebo |
| Raised triglycerides | lowers triglycerides | in the same meta-analysis −0.25 mmol/L, CI −0.45 to −0.06 (−22.4 mg/dL, CI −39.7 to −5.0; p = 0.01) |
| Inflammation | lowers high-sensitivity C-reactive protein, a marker of inflammation | in the same meta-analysis −1.7 mg/L, significant; heterogeneity between studies is zero — the most robust result |
| Blood sugar | lowers fasting glucose | the reduction is confirmed in meta-analysis |
| Vitamin C | fresh fruit contains 252 mg per 100 g — 5.9 times more than an orange (42.7 mg), measured by one laboratory using one method | — |
How it helps
Cholesterol and triglycerides
A meta-analysis of nine randomised trials in 535 participants exists. Doses ranged from 500 to 1500 mg a day, duration from two to twelve weeks. Compared with placebo, amla significantly lowered LDL-C, triglycerides and VLDL-C — the figures are in the Key points table.
Inflammation and blood sugar
The C-reactive protein result deserves separate mention. Heterogeneity there is zero — the inflammation finding is more robust than the lipid one, though it gets discussed far less. A reduction in fasting glucose is also confirmed in meta-analysis.
Vitamin C: 5.9 times more than an orange
A sound comparison is one where both fruits are measured by the same laboratory, by the same method, and published in the same book. The Indian food composition tables do exactly that: amla 252 mg per 100 g, orange 42.7 mg. A 5.9-fold difference. Take the USDA figure for orange, 53 mg, and the gap is 4.7-fold. Six times is still a lot, and it is true.
The popular «twenty times» is a legend: it comes from an older value of 600 mg per 100 g, published in 1951 and copied from source to source ever since. The same book that reports the modern measurement of 252 mg cites the 1951 figure as a historical note, not as its own finding.
Who it suits
- Moderately raised LDL-C and triglycerides, statins not indicated — reasonable alongside lifestyle measures.
- Raised C-reactive protein — reasonable; this is the most robust result.
How to take it
An extract is more effective than a powder, and the reason is concentration. A 10:1 ratio means ten parts of raw material yield one part of preparation. A capsule of extract carries more active compounds than the same weight of simply dried and ground fruit, which is why extract doses differ from powder doses.
50 capsules per jar. Follow the manufacturer's dosing rather than trying to convert capsules into grams of fruit from a study.
Who should see a doctor first
| Situation | Reasonable? |
|---|---|
| Taking antiplatelet or anticoagulant drugs | Only on a doctor's decision |
| On glucose-lowering therapy | Only with glucose monitoring |
| Surgery planned in the coming weeks | No |
| Pregnancy, breastfeeding | No |
| Goal is to replace a statin | No — no data support that |
Bottom line
Amla is a rare supplement whose real data are more interesting than its legends: a meta-analysis of nine randomised trials shows reductions in LDL-C, triglycerides and a marker of inflammation, and fresh fruit has 5.9 times the vitamin C of an orange. Its place is alongside lifestyle measures and, if your doctor agrees, alongside therapy. What works for raised cholesterol beyond supplements, and when statins are genuinely needed, is covered separately: cholesterol without statins.
The thing most worth remembering, and the thing least often written: amla affects blood clotting, and with blood-thinning medicines its action adds to theirs. If you take those, this is a conversation with your doctor before the first capsule, not after.
Caveats
- HDL-C. No proven effect: +0.05 mmol/L, CI −0.02 to +0.13 (+2.1 mg/dL, CI −0.9 to +5.1), p = 0.17. The discussion section of the same paper mistakenly lists HDL-C among the significant results — the figures in the results section are the correct ones. A second meta-analysis reaches the opposite conclusion on this measure — the question is open.
- Heterogeneity. For LDL-C the studies diverge sharply, and the prediction interval — the range a result in a new population would fall into — crosses zero: on average there is an effect, but in a given person it may turn out to be nil.
- Quality. Not one of the nine studies was rated at low risk of bias. Seven of the nine were conducted in India and four came from a single research group, so the data are less independent than the count suggests. Publication bias could not be assessed: too few studies.
- Effect size. An LDL-C reduction of 0.39 mmol/L (15 mg/dL) is roughly a tenth of what an average statin dose delivers; the result was measured on a surrogate marker, not on outcomes such as heart attack or mortality. It cannot replace a medicine.
- Other directions. The size of the fasting-glucose reduction cannot be stated: the available publication reports significance levels only. For HbA1c no pooled estimate exists — only individual small trials. Endothelial function — one double-blind trial in 59 participants with metabolic syndrome, on a surrogate measure, funded by the manufacturer. For body weight no placebo-controlled trials were found.
- Vitamin C. For fresh fruit, values across sources range from 155 to 600 mg per 100 g, nearly fourfold, so a ratio cannot be presented without naming the source. There is not a single measurement of vitamin C in dried extract; how much survives drying and storage is unknown — even the correct ratio describes fresh fruit, not a capsule.
- The 10:1 ratio. It cannot be converted into trial doses: no clinical study of amla used a 10:1 extract. Trials standardised by polyphenols (at least 35%), ellagitannins (1.2–1.5%) and hydrolysable tannins (at least 60%). How much active substance an extract contains depends on cultivar, ripeness, solvent and drying. Under European rules for herbal preparations the correct way to state a ratio is as a range, such as «5–8:1», because extraction yield varies between batches; a round «10:1» is a consumer-facing form.

Key facts
- Meta-analysis of nine RCTs (535 participants, 500–1500 mg a day): LDL-C falls by a mean of 0.39 mmol/L (15.1 mg/dL), triglycerides by 0.25 mmol/L (22.4 mg/dL), VLDL-C by 0.14 mmol/L (5.4 mg/dL).
- Inflammation: high-sensitivity C-reactive protein falls by 1.7 mg/L, and heterogeneity between studies here is zero — this is the most robust result.
- Vitamin C: measured by one laboratory using one method, fresh amla contains 252 mg per 100 g and orange 42.7 mg — 5.9 times more; «twenty times» is a legend.
- A 10:1 extract is more concentrated than a powder: a capsule delivers more active compounds than the same weight of dried fruit. 50 capsules per jar.
- Amla has a demonstrated antiplatelet effect in humans: it prolongs bleeding time, and in the only interaction study the effect was not abolished by concurrent clopidogrel or aspirin — on such drugs, see a doctor first.
