How Does Berberine Help with Blood Sugar & Metabolic Health?

Activates AMP-activated protein kinase (AMPK), the body's metabolic master switch. Improves insulin sensitivity, reduces hepatic gluconeogenesis (liver glucose production), inhibits intestinal glucose absorption, upregulates LDL receptors in the liver (independent of statin pathways), and beneficially modulates gut microbiota composition. Also inhibits CYP3A4 and P-glycoprotein, which causes significant drug interactions.

Berberine HCl is the standard form. Start with 500mg once daily for 1-2 weeks to minimise GI side effects. Most clinical trials use 1500mg/day divided into 3 doses. Effects on HbA1c comparable to metformin in head-to-head trials.

This link is supported by 4 clinical studies, with the evidence rated as strong overall. With an effectiveness rating of 5/5, Berberine is one of the top-rated supplements for blood sugar & metabolic health.
