Best berberine supplements for metabolic support

Berberine products compared on published dose, botanical sourcing and standardisation — plus the drug interaction issue their marketing omits.

Berberine has the strongest ingredient-level research in this category and the most misleading nickname. It acts on AMPK, not the GLP-1 receptor. It also inhibits CYP3A4 and can raise blood levels of common prescription medications, which makes it a pharmacist conversation before it is a shopping decision.
