Berberine and Diabetes — How It Works, What the Studies Show, and Safe Dosing

A 2022 meta-analysis of 37 randomized trials found that berberine lowered glycated hemoglobin by 0.63% and fasting glucose by 0.82 mmol/L, with consistent results across diverse patient groups Earlier researchers also highlighted how berberine lowers blood sugar and harmful blood fats while also reducing liver fat and markers linked to kidney damage Berberine limits fat cell development and dampens inflammation as well, effects that may support weight control and improved insulin sensitivity In a 13‑week randomized study, researchers showed that berberine's blood sugar-lowering abilities are on par with the effects of the diabetes drug metformin Clinical studies support taking 500 mg of berberine with meals up to three times daily, starting with lower doses and increasing gradually; however, there are safety precautions to keep in mind
