Berberine
MetabolicKey Benefits
How It Works
Berberine activates AMPK (the same pathway as metformin and exercise), improving glucose uptake and insulin sensitivity. It also inhibits PCSK9 (lowering LDL cholesterol), modulates gut microbiota composition, and has antimicrobial properties.
Dosage & Timing
Recommended Dosage
500 mg 2-3 times daily with meals (1,000-1,500 mg total)
Best Time to Take
With meals to reduce GI effects and match glucose response
Recommended Form
Berberine HCl or dihydroberberine (GlucoVantage)
Side Effects
GI discomfort is common initially (diarrhoea, cramping). May cause constipation. Can lower blood sugar significantly.
Drug Interactions
STRONG interaction with many medications via CYP enzyme inhibition. Interacts with diabetes drugs, blood thinners, antibiotics, and cyclosporine.
What Does The Research Say?
Head-to-head trials show comparable glucose-lowering to metformin. Reduces HbA1c by 0.5-1.0%. Also lowers LDL cholesterol and triglycerides. GlucoVantage (dihydroberberine) has improved bioavailability with fewer GI effects.
