Choose brands tested:
ConsumerLab, NSF or USP

Examine for arsenic contamination or lead.
3. Look for formulas with enhanced absorption.
Regular berberine has poor bioavailability (~1%). Beware of:

Dihydroberberine DHB is a version that is more bioavailable and long-lasting (GlucoVantage trademarked version).
Liposomal berberine - Best for gut-sensitive individuals.
4. Dosage Optimal (500-1500mg daily, divided doses)
Standard dosage: Take 500mg twice every day with meals, to mimic the effects of glucose-lowering seen in studies.
Dihydroberberine (DHB): Lower dose needed (~100-300mg, 2x/day).
Avoid doses that exceed 2000mg per day, unless under medical supervision. (Can alter the gut bacteria).
5. Ingredients that combine for enhanced effects
Alpha-lipoic acid (ALA) boosts the sensitivity of insulin.
Chromium picolinate helps in glucose metabolism.
Ceylon cinnamon - Enhances blood sugar control.
Milk Thistle (silymarine) - Protects liver (berberine, which is processed by liver),
