Berberine improves metabolic markers with modest weight effects.
Overview
Verdict
How It Works
Dosing & Protocol
Typical dose
- Recommended dose
- 500mg two to three times daily with meals
- Expected timeframe
- 12 weeks
Protocol
- studied dose
- 500 mg two to three times daily with meals for 12 weeks
- evidence note
- Verdict is insufficient as a weight loss agent - the weight change is a side effect of metabolic improvement, not a reliable fat loss effect
- what happened
- Meta-analyses show reductions in BMI and waist circumference, mostly in metabolic syndrome populations, averaging around 2 kg. Trials in people without metabolic dysfunction do not show this
- what to do instead
- A sustained calorie deficit and resistance training, with berberine as an optional add-on if your glucose markers are also poor
- if you still trial it
- 500 mg with the largest meal, building to 1500 mg/day over three weeks, judged at 12 weeks on waist and HbA1c rather than the scale alone
