Magnesium is an essential mineral for many fundamental processes in the body. It normally exists in the body as a charged particle (or ion) and is primarily stored in bones. Magnesium plays an integral role in hundreds of enzymatic functions and is important for nerve, muscle, and bone health.

Magnesium helps with the absorption of calcium and depends on vitamin D for its own absorption. Food dietary sources of magnesium include spinach, legumes, nuts, and grains.

The recommended dietary allowance for magnesium is 400mg/d for men and 310mg/d for women. Excessive intake can lead to gastrointestinal discomfort, but no adverse effect has been seen for long-term consumption of amounts less than or equal to 700mg/d.
