Is hypotension is a deficiency of magnesium?

Hypotension can occur for many different reasons. Causes include (but are not limited to) dehydration, anemia, medication side effects, a result of injury to the brain or spinal cord, or (oddly enough) meditation. This means it would be wrong to state that "hypotenison is always caused by a magnesium deficiency" or "all hypotensive patients would benefit from taking magnesium".
