Amla (Indian Gooseberry)

One of the better-supported Ayurvedic botanicals: two independent meta-analyses find consistent improvements in cholesterol, fasting glucose, and CRP. Trial quality is modest and most studies come from a single region, so treat the effect sizes as provisional.

What the science says

  • Lipid profile Moderate evidence

    A meta-analysis of 5 RCTs found amla supplementation significantly reduced LDL, total cholesterol, and triglycerides while raising HDL (all p < 0.001). Participants were typically aged 40-58 with a mean BMI of 25.5, and interventions ran 3-12 weeks. An independent 2023 systematic review of Emblica officinalis RCTs reached broadly similar conclusions on lipids.

  • Fasting glucose and inflammation Moderate evidence

    The same meta-analysis reported significant reductions in fasting blood glucose (p < 0.001) and C-reactive protein (p = 0.002). The independent review flagged high risk of bias across the included trials and a small total sample, so these should be read as consistent but not definitive.

  • Amla as a vitamin C source Limited evidence

    Amla is marketed as a natural vitamin C powerhouse, but the ascorbate content of dried commercial powders is highly variable and degrades with processing. Much of the measured antioxidant activity comes from hydrolysable tannins (emblicanin A and B) that interfere with common vitamin C assays rather than acting as ascorbate in the body.

Dosage & safety

Studied dose500-1,000 mg/day of standardized aqueous fruit extract, or 1-3 g/day of dried fruit powder, for 8-12 weeks in most trials. Extract standardization varies widely (often to tannins or to gallic acid), so match the product to the trial format where you can.
SafetyUsually well tolerated; loose stools and acid reflux are the common complaints. Amla shows antiplatelet activity in vitro and in small human studies — caution with warfarin, DOACs, and aspirin, and stop it before surgery. It may lower blood glucose additively with antidiabetic drugs. Ayurvedic polyherbal products containing amla have repeatedly been implicated in lead, mercury, and arsenic contamination; single-ingredient products with third-party heavy-metal testing are strongly preferable. Not studied in pregnancy.

How to take it

TimingTiming does not matter.
With food?Take it with food - it is very acidic and reflux is a common complaint.
Worth knowingChoose single-ingredient, third-party heavy-metal-tested product; the lead, mercury and arsenic problem is concentrated in polyherbal Ayurvedic formulas that contain amla.

Interactions

With medications

  • warfarin, DOACs and aspirin

    Amla has antiplatelet activity in vitro and in small human studies, adding to bleeding risk. tell your prescriber and stop it before surgery

  • insulin and other antidiabetic drugs

    Amla lowers blood glucose additively. monitor your glucose when starting

With other supplements

  • fish oil, garlic and ginkgo

    Additive antiplatelet effect. do not stack them around surgery

Well-established interactions only — this is not a complete list. Always tell your doctor and pharmacist what you take.

Frequently asked questions

Does amla lower cholesterol?

Amla has moderate evidence: a meta-analysis of 5 trials found it significantly lowered LDL, total cholesterol and triglycerides while raising HDL, and an independent review broadly agreed. Trial quality is modest and most studies come from a single region.

Does amla help blood sugar?

The same meta-analysis found amla significantly reduced fasting blood glucose and C-reactive protein. An independent review flagged high risk of bias and small samples, so treat this moderate evidence as consistent but not definitive.

Is amla a good natural source of vitamin C?

Not reliably: the vitamin C content of dried amla powders is highly variable and degrades with processing. Much of amla's measured antioxidant activity comes from tannins that interfere with vitamin C assays.

Is amla safe with blood thinners?

Amla has antiplatelet activity, so tell your prescriber if you take warfarin, DOACs or aspirin and stop amla before surgery. Choose single-ingredient, heavy-metal-tested amla, since polyherbal Ayurvedic products containing it have been contaminated with lead, mercury and arsenic.
