Forms Comparison

FormBioavailabilityBest For
Berberine HCl CapsulesModerateStandard supplementation — most common and studied form
Berberine PhytosomeHighEnhanced absorption — lipid-bound for improved bioavailability
Dihydroberberine (DHB)High (5x berberine HCl)Lower dose needed — active metabolite with superior absorption
Berberine + Bitter MelonModerateSynergistic blood sugar support — combines two glucose-lowering compounds
Berberine + Milk ThistleModerateLiver support — milk thistle may offset berberine's hepatic effects
