Higher Blood Magnesium Levels Linked to Lower Incidence of Hypertension, Cardiovascular Disease, and Type 2 Diabetes

From the abstract of a recent meta-analysis:

“Magnesium (Mg) is the second most predominant intracellular electrolyte, following after potassium. Mg serves as an important cofactor in many essential enzymatic reactions involved in glucose metabolism and several essential physiological processes, including modulating vascular smooth muscle tone and endothelial cell function. The role of Mg in the development and progress of T2DM and cardiovascular diseases (CVD) has drawn researchers’ attention in the recent decades. Several large prospective cohort studies have shown that low Mg intake is associated with incidence of T2DM and CVD. Notably, because Mg intake was usually assessed based on self-administered food frequency questionnaires, misclassification is inevitable. In addition, dietary Mg could not represent the accurate amount of Mg intake without considering the substantial loss during food processing and cooking. Moreover, the health impact of Mg is difficult to be distinguished from intake of other nutrients such as calcium, potassium, phosphorus, and fiber.”
