Berberine ： Insulin Resistance
A エビデンス 複数の大規模臨床試験が一貫して有意な効果を示しています。Meta-analysis of 27 RCTs found significant improvements in fasting glucose, HbA1c, and insulin sensitivity. AMPK activation is comparable to metformin. A landmark RCT (n=116) showed 500 mg 3x/day reduced body weight by 3.6 kg and triglycerides by 35.9%.
