Dietary Magnesium and Mortality: What a Meta-Analysis of a Million Adults Found

A dose-response meta-analysis published in BMC Medicine in 2016 pooled data from forty prospective cohort studies involving over one million participants and found that each one-hundred-milligram-per-day increase in dietary magnesium intake was associated with a twenty-two percent lower risk of cardiovascular disease, a nineteen percent lower risk of type 2 diabetes, and a ten percent lower risk of all-cause mortality. The estimates were consistent across studies from multiple countries and across sex. Meanwhile, surveys consistently show that approximately fifty percent of adults in the United States do not meet the recommended dietary allowance for magnesium — a mineral found abundantly in leafy green vegetables, legumes, nuts, and whole grains that has largely disappeared from the conversation about cardiovascular and metabolic health. Magnesium is the fourth most abundant mineral in the human body and a cofactor for over three hundred enzymatic reactions — including those involved in DNA synthesis, protein synthesis, energy production, and the regulation of calcium and potassium transport across cell membranes. Despite this central role in cellular physiology, magnesium occupies a peripheral position in most discussions of cardiovascular and metabolic health, overshadowed by sodium, potassium, and calcium.
