Berberine para Insulin Resistance

A Evidências Vários grandes ensaios clínicos mostram de forma consistente benefícios significativos.

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%.
