Berberine

Berberine structure

Overview​

Berberine is a polyphenolic alkaloid that supports glycemic control, has antimicrobial effects, and modulates the microbiome. It is part of glucose regulation strategies and SIBO suppression protocols. Note: Berberine is typically consumed as a supplement (from plants like barberry, goldenseal, or Oregon grape) rather than from common dietary foods in meaningful amounts, which is why no foods are listed below.

Recipes​
