How Does Berberine Help with Weight Loss & Metabolism?

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 activates AMPK, the "metabolic master switch," increasing fat oxidation and reducing fat storage. Multiple RCTs show 2-3kg more weight loss vs placebo over 12 weeks. Effects are comparable to metformin in head-to-head trials. Start with 500mg once daily for the first week to minimise GI side effects (diarrhoea, cramping).
