PMID: 25006989

How Does Berberine Help with Gut 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.

Modulates gut microbiota composition. May help with SIBO. Can cause initial GI discomfort.
