Magnesium is important for skeletal development and maintaining electrical potential in nerve and muscle membranes. Magnesium also acts as a co-factor for enzymes requiring ATP, and it is closely involved with calcium in metabolism. an essential mineral nutrient for life and is present in every cell type in every organism.
Food sources of magnesium include cereals, leafy green vegetables and soybeans, raw nuts and fruit. As with most nutrients, daily needs for magnesium are unlikely to be met by one serving of any single food. Eating a wide variety of fruits, vegetables, and grains will help ensure adequate intake of magnesium.
Inadequate magnesium intake frequently causes muscle spasms and has been associated with cardiovascular disease, diabetes, high blood pressure, anxiety disorders, migraines, osteoporosis, and cerebral infarction. Acute deficiency (hypomagnesemia) is rare and there is no evidence that large dietary intakes are harmful to humans with normal renal function.
