Berberine

Also known as: berberine HCl, berberine hydrochloride

A bioactive alkaloid found in several plants including goldenseal, barberry, and Oregon grape. Used for blood sugar management, metabolic health, and PCOS-related insulin resistance. Some research compares its glycaemic effects to metformin, though it is not a licensed medicine in the UK.

Research Context

Research context compiled from published sources

How does Berberine work?

Activates AMP-activated protein kinase (AMPK), a central metabolic regulator. This stimulates glucose uptake, improves insulin sensitivity, reduces hepatic glucose production, and promotes fatty acid oxidation. Also modulates the gut microbiome and may reduce intestinal glucose absorption.
