Dual berberine formula: 450mg berberine HCl plus 550mg berberine phytosome. The phytosome form provides dramatically enhanced absorption (up to 5x), making the effective berberine delivery significantly higher than the 1000mg total would suggest. This approaches clinical protocol doses (1500mg/day berberine) in a single capsule thanks to the phytosome technology. Thorne quality assurance. For blood sugar and metabolic support, this is one of the best berberine products available.

Thorne Berberine 500mg: the formulation holds up. Lead: Berberine HCl at 450 mg. Dual berberine formula: 450mg berberine HCl plus 550mg berberine phytosome. Clinical dose on the primary, and the panel holds together.
Blood sugar and metabolic support.. The database missed the mark on this one. You are getting a full clinical dose of the bioavailable phytosome form plus a solid hit of standard HCl. This actually works for those who find basic berberine too weak.
