镁离子是人体细胞内第二丰度的阳离子,在维持细胞正常代谢及功能发挥中起着重要作用。通过镁潴留试验发现糖尿病、高血压、高血脂等具有代谢综合征特点的患者广泛存在镁缺乏。且血镁浓度与血糖、血浆胰岛素、血压、血脂等代谢指标呈负相关.补镁后能改善上述异常指标。由于多代谢综合征在人群中的高发病率,故在人群中补镁可能有助于减少该综合征的发生。 Magnesium ions are the second abundant cation in human cells and play an important role in maintaining the normal metabolism and function of cells. Magnesium retention test found that diabetes, hypertension, hyperlipidemia and other metabolic syndrome characterized by widespread magnesium deficiency in patients. And serum magnesium concentration and blood glucose, plasma insulin, blood pressure, blood lipids and other metabolic indicators was negatively correlated after magnesium supplementation can improve the above abnormal indicators. Due to the high incidence of multiple metabolic syndrome in the population, supplementation of magnesium in the population may help reduce the incidence of the syndrome.
