Magnesium affects migraines?

MAGNESIUM:
"Magnesium is a mineral that has been used widely for treating abdominal cramps and constipation. It is obtained naturally from the diet, and is required for many metabolic activities in the body. Absorption of magnesium is reduced by high intake of calcium, alcohol, surgery, diuretics, liver or kidney disease, and oral contraceptive use.

While small doses of magnesium-containing laxatives are safe, larger doses may not be. This is especially true for long-term use.

Fatigue, fibromyalgia, migraine, premenstrual syndrome, and dysmenorrhea are conditions associated with magnesium deficiency. Women with premenstrual syndrome who were found to have low magnesium were more likely to have excess sensitivity to pain with generalized aches and pains."

My Take:

One more thing to investigate and perhaps supplement.
