Summary

Berberine is a plant-derived alkaloid that activates AMPK and influences glucose and lipid metabolism, with effects sometimes compared to metformin in smaller trials. It is often used for blood sugar and lipid support in people with metabolic concerns. Because it affects drug-metabolizing enzymes, it has a higher potential for interactions than many other supplements.
