What this is
The 'nature's Ozempic' TikTok rebrand inflated hype beyond evidence. Legitimate mechanism and moderate effects on glucose and lipids. CYP3A4 interactions are underappreciated — affects many common drugs including statins, calcium channel blockers, warfarin. Poor bioavailability native — dihydroberberine has better PK.
Mechanism
Alkaloid from Berberis/goldenseal/Coptis; AMPK activator (metformin-like); inhibits PCSK9 expression; modulates gut microbiome; glucose-lowering via multiple mechanisms
Dose & route
500 mg 2-3x/day with meals; dihydroberberine (Glucovantage) claims better bioavailability
