Thorne Berberine, 60 Capsules

Berberine is one of the most talked-about plant compounds in health right now — a natural alkaloid found in plants like barberry, used for centuries in traditional Chinese and Ayurvedic practice. Thorne's version is the one the careful people buy. Why Thorne? Because this is the brand that supplies U.S. Olympic teams and gets third-party tested to a standard most supplement brands never touch. Their formula pairs berberine phytosome — a form designed for better absorption — with berberine HCl, to help support healthy blood sugar levels already in the normal range, metabolic health, and a balanced gut. No unnecessary fillers, no mystery blends, and it's NSF Certified for Sport. Who it's for: anyone working on metabolic health who reads labels and wants the premium, verified option instead of the cheapest bottle on the shelf. It costs more. With Thorne, you can see where the money went.
