Magnesium plays an essential role in a wide range of fundamental cellular functions. More than 300 enzyme pathways require magnesium as a cofactor. When complexed with adenosine triphosphate (ATP), the main carrier of metabolic energy in the body, magnesium is essential for several essential biological processes. Clinically, magnesium can be recommended as a laxative, for various cardiovascular diseases, diabetes, fatigue, fibromyalgia, migraine, osteoporosis, restless leg syndrome, insomnia, and for increased stamina in athletes. It is estimated that a significant portion of the American population is deficient in magnesium. Low levels of magnesium can be caused by gastrointestinal or renal loss due to incomplete reabsorption. Other causes of magnesium loss can be from excessive intake of alcohol, sugar, fiber, caffeine and laxatives. Many medications create a depletion of magnesium, including: oral contraceptives, estrogens, loop diuretics, thiazide diuretics, digoxin, tetracycline and several other antibiotics. In fact, many of the common adverse effects seen with these medications correspond with the symptoms of magnesium depletion. These include: muscle cramps, weakness, insomnia, anxiety, confusion and depression. The recommended daily allowances for magnesium are 410-420 mg/day for men and 310-360 mg/day for women.
