Dihydroberberine (dhBBR), a derivative of berberine, exhibits significantly improved in vivo efficacy, reduced adiposity, and improved insulin sensitivity compared to berberine at equivalent lower doses.

Dihydroberberine (dhBBR) is a derivative of berberine that is much better absorbed by the body. In rodent studies, dhBBR was significantly more effective at reducing fat and improving insulin sensitivity than standard berberine at the same dose. This suggests that for metabolic benefits, the form of berberine (bioavailability) is critical.

GoodSupportsHIGH confidence
Strikingly, one derivative (dhBBR) displayed similar potency to BBR to stimulate both glucose uptake and AMPK... and hence its effects were examined in rodent models of insulin resistance.
