Dihydroberberine

Dihydroberberine is a more bioavailable form of berberine with ~5x better intestinal absorption and lower risk of GI distress. Evidence from berberine trials (applicable due to conversion - DHB converts back to berberine after absorption) shows significant effects on blood glucose, HbA1c, and lipid profiles comparable to metformin. Works via mitochondrial complex I inhibition leading to AMPK activation. Important drug interactions with CYP450 substrates and diabetic medications.
