Cramps?

 According to Dr. Oz, Dr. Weil, the Mayo Clinic, and other leading authorities, magnesium deficiency is the major hidden cause of muscle cramps throughout the entire body (including leg and foot cramps), and no prescription medication can fix it. 
 In fact, 78% of muscle cramp sufferers have a severe magnesium deficiency. Without magnesium, your body is missing its most important natural defense against pain, swelling, tension and inflammation.  
 Studies show that aggressively fixing a magnesium deficiency can eliminate muscle cramps and prevent them in the future.
