Magnesium is effective for treating muscle cramps. It helps stabilize cell membranes and is important for energy production, cell growth, and protein formation. Cramps occur due to involuntary muscle contractions that briefly stay flexed. Low levels of electrolytes like magnesium, calcium, potassium, and sodium from sweating or certain drugs and medical conditions can cause cramps. Consuming a diet high in magnesium and vitamin E through foods and supplements can help prevent cramps by maintaining electrolyte levels.
