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]
