The mineral magnesium is important for every organ in the body, particularly the heart, muscles, and kidneys. It also contributes to the composition of teeth and bones. Most importantly, it activates enzymes, contributes to energy production, and helps regulate calcium levels as well as copper, zinc, potassium, vitamin D, and other important nutrients in the body.

Magnesium levels tend to be lower in those with migraine headaches, including children and teenagers, when compared to those with tension headaches or no headaches at all. In addition, a few studies suggest that magnesium supplements may decrease the length of time that one suffers from a migraine and reduces the amount of medication needed.

Some experts suggest that oral magnesium may be an appropriate alternative to prescription medication for people who suffer from migraine headaches. Other experts suggest that combining magnesium with the herb feverfew along with vitamin B2 (riboflavin) may be particularly helpful when you have a headache.

People with diabetes tend to have lower magnesium levels compared with those who have normal glucose tolerance. Supplementation with magnesium overcomes this problem and may help some diabetics improve glucose tolerance.

Warnings
Taking too much magnesium often leads to diarrhea. For some people this can happen with amounts as low as 350–500 mg per day. More serious problems can develop with excessive magnesium intake from magnesium-containing laxatives. However, the amounts of magnesium found in nutritional supplements are unlikely to cause such problems. People with kidney disease should not take magnesium supplements without consulting a doctor.
