Many processes in the body require magnesium. It is essential for all biosynthetic processes and for the formation of energy molecules.A marginal deficiency of magnesium results in nausea, muscle weakness, irritability, mental derangement, and other muscular changes. Because magnesium assists in calcium and potassium uptake, decreased supplies of magnesium will result in lower levels of calcium and potassium. The proper magnesium concentration is needed to maintain proper heart function. Moreover, if magnesium is given to patients during the first few days following their heart attacks, a decrease in mortality is seen thereafter. It is equally important to make sure that your magnesium levels are adequate if you are receiving digitalis, a cardiovascular drug. It has been shown that patients receiving digitalis have low magnesium levels. Low levels of magnesium are frequently seen in diabetics as well. When diabetic patients were given magnesium, their glucose levels were much better controlled and less insulin was required.*35\360\2*
