Thorne Berberine Review 2026: Worth the Price?
Hype Score
Thorne Berberine-500 is a well-formulated supplement combining two forms of berberine (HCl and phytosome) with clinical support for metabolic, cardiovascular, and glucose health. The product uses appropriately hedged language, specifies all ingredient doses, and includes third-party testing. However, some claims (hormone balance, skin health) lack strong evidence, and the berberine HCl dose is on the lower end of the therapeutic range—though the recommended dosing (1-2 capsules twice daily) brings it into the effective range. Pricing is moderate for a premium supplement brand.
Bottom line: This is a legitimate, well-made berberine supplement with solid clinical backing for metabolic support, but you're paying a premium for the brand and phytosome formulation—generic berberine HCl would work similarly at lower cost.

Alternative
Berberine HCl wholesale cost ~$0.08-0.12/dose. Phytosome formulation adds value through enhanced absorption. At $1.47/serving with ~$0.15-0.20 ingredient cost, markup is approximately 7-10x, which is reasonable for a premium supplement brand with third-party testing and quality assurance. Thorne is a reputable manufacturer, which justifies moderate premium pricing.
