Who Needs Magnesium Supplements?

In addition, certain medications can reduce magnesium levels including antibiotics, bisphosphonates, calcium channel blockers, muscle relaxants and diuretics.
Symptoms of Magnesium Deficiency
Symptoms of magnesium deficiency include poor appetite, nausea and vomiting, and fatigue and weakness. A simple blood test can confirm a magnesium deficiency. In cases of sever magnesium deficiency, individuals may have lower levels of both calcium (hypocalcaemia) and potassium (hypokalemia) in their blood.
