Evidence standard: We separate merchant statements from independent health evidence. This page is educational, not medical advice.
Bottom line
NCCIH says berberine is likely unsafe for infants and may be unsafe during pregnancy or breastfeeding because of possible effects on the fetus or infant. People taking medicines also need to consider interactions.
This is not an exhaustive contraindication list. Health conditions, surgery and other supplements can change the risk picture, so individualized professional advice matters.
