Evidence-backed FAQ

Does berberine lower blood sugar?

Direct answer

In adults with type 2 diabetes, pooled randomized-trial evidence suggests berberine may be associated with lower fasting blood glucose. This evidence does not establish a benefit for healthy people or replace prescribed treatment.[1]

What the evidence shows

The evidence is specific to adults with type 2 diabetes and comes mainly from small, heterogeneous trials of limited quality.[1]

Important limitations

The pooled trials showed heterogeneity and signs of publication bias, and the result should not be generalized beyond the studied population.[1]
