Zinc per Insulin Resistance
B Evidenze Almeno un trial randomizzato lo supporta, con risultati per lo più coerenti.Meta-analysis of 27 RCTs (n=1,652) found zinc supplementation significantly reduced body weight (0.63 kg), BMI, waist circumference, and HOMA-IR. Separate meta-analysis found significant reductions in fasting glucose, HbA1c, and insulin. Effects are strongest in deficient and obese individuals.
