Magnesium is needed in biochemical reactions, including energy production, nutrient metabolism, fatty acid and protein synthesis, transmission of nerve and muscle impulses, glucose control, blood pressure regulation and transport of calcium and potassium ions. Higher levels of serum magnesium have been associated with reduced risk of cardiovascular disease. Evidence supports an inverse relationship between dietary intake of magnesium and risk of Type 2 diabetes. One large cohort study showed magnesium intake may aid in preventing pancreatic cancer.
Magnesium is widely available in plant and animal foods and often is included in fortified foods and enriched grains. Soil health can impact the amount of magnesium in foods.
