Berberine (HCl, dihydroberberine)
Plant alkaloid with metabolic effects — lowers fasting glucose and LDL in multiple meta-analyses. Drug interactions exist.
How it works
Berberine activates the enzyme AMPK, the same cellular energy sensor triggered by exercise and metformin. This improves insulin sensitivity, lowers blood sugar and lipids, and shifts the gut microbiome. Its effect on glucose metabolism has repeatedly been compared to metformin.
