Magnesium ： Metabolic Syndrome

B エビデンス少なくとも1件のランダム化試験がこれを支持しており、おおむね一貫した結果が得られています。

Meta-analysis of 32 RCTs (n=2,382) found significant reductions in BMI, waist circumference, fasting glucose, and CRP. Each 100 mg/day increase in magnesium intake was associated with 5% lower metabolic syndrome risk. Up to 68% of Americans fail to meet the RDA.
