A meta-analysis indicated that magnesium (Mg) supplementation may lower blood pressure (BP) in normotensive or hypertensive adults. The study included 34 randomized double-blind placebo-controlled trials involving 2028 participants. Mg supplementation at a median dose of 368 mg/d for a median duration of 3 months significantly reduced systolic BP by 2.00 mm Hg and diastolic BP by 1.78 mm Hg; these reductions were accompanied by 0.05 mmol/L elevation of serum Mg compared with placebo. Serum Mg was negatively associated with diastolic BP but not systolic BP. Mg-rich foods, such as fish, shrimp, eggs, chicken, nuts, and leafy greens, should be encouraged in hypertensive patients.

一项荟萃分析表明，补镁可降低血压正常者或高血压患者的血压。该研究包括34个随机，双盲，安慰剂对照试验，共2028人。与安慰剂相比，中位剂量补镁368毫克/天平均3个月，显著降低收缩压2.00毫米汞柱和舒张压1.78毫米汞柱;血压下降伴随着血清镁升高0.05毫摩尔/升。血清镁与舒张压呈负相关，而非收缩压。应鼓励高血压患者食用富含镁的食物，如鱼，虾，鸡蛋，鸡肉，坚果和绿叶蔬菜。来源：http://hyper.ahajournals.org/
