What Are the Uses of Magnesium Oxide?
Magnesium oxide is an over-the-counter dietary supplement that you take if you have low levels of magnesium in your body. The Linus Pauling Institute explains that magnesium is stored in your bones and muscles, and plays a crucial role in energy production as well as muscle and nerve function. People who are not deficient in magnesium may still use the supplement, in the hope of gaining health benefits.
