What are the physical signs of magnesium deficiency?

Common signs and symptoms of magnesium deficiency include leg cramps, migraines, and fatigue. Other signs including arrhythmias, loss of appetite, depression, muscle contractions, and coronary spasm may also be seen in patients with low magnesium levels.

Not all people experience the signs of magnesium deficiency. In addition, blood tests are not always accurate because less than 1% of the body's magnesium is located in the blood. The majority of the body's magnesium is located in muscle and bone. Therefore, if you have patients with signs of (or are at risk for) magnesium deficiency, they would benefit from taking two tablets daily of Mag-Ox 400.
