Magnesium is the most prevalent mineral in our cells. It helps control a vast number of chemical reactions in our metabolism. All chemical reactions are controlled by enzymes, and most enzymes work together with minerals, magnesium being one of them. Magnesium is an integrated part of more than 300 enzyme reactions in our body.Magnesium is important for the normal functioning of the heart, skeletal muscles and nerves, and in the processes which supply the body with energy. Magnesium is important for bone and tooth formation, and for normal blood clotting.Magnesium is very important for ATPase, an enzyme that enables cells to utilize an energy substance called adenosine triphosphate, ATP for their different functions. The heart contains extremely large quantities of magnesium, where it helps maintain the electric voltage across the membranes of the nerve and muscle cells, which is the basis of their functioning. Without magnesium our heart, muscles and nerves lose strength. Magnesium is needed for proper control of the body weight because it plays an active role in the metabolism.
