Magnesium is an essential mineral needed by the body for a number of functions. It helps to build healthy bones and teeth, is necessary for electrolyte balance and helps to convert the food we eat into energy. Magnesium is also necessary for muscle function (including function of heart muscle) and for a healthy nervous system.
