Berberine

Herbal

Also known as: Berberine HCl, BBR

Berberine is a bioactive compound extracted from several plants including goldenseal and barberry. It activates AMPK (a metabolic master switch) and has been shown to rival metformin for blood sugar control.

Best Timing

Take with meals to reduce GI side effects and time with glucose absorption. Split into 2–3 doses — short half-life.

Absorption

Poor bioavailability (~5%). Dihydroberberine is 5x better absorbed. Always take with food. GI side effects decrease over time.

Efficacy of berberine in patients with type 2 diabetes

Yin J, Xing H, Ye J. - Metabolism (2008)

500mg berberine 3x/day for 3 months lowered HbA1c from 9.5% to 7.5% — comparable to metformin in the same study.
