Magnesium is an important mineral necessary for many functions in the body, including chemical reactions, muscle contraction, blood clotting, blood pressure regulation, and bone development. The body cannot make magnesium; therefore our needs must be met through the diet. While the majority of our magnesium supply is stored in the bones, some is found in the muscles and body fluids. When blood levels of magnesium are low, the body pulls magnesium from the bones to correct the imbalance.*
