Twenty-five million Americans suffer from migraines. Statistically, more women experience migraines than men, especially in the twenty-to-fifty-year-old age group. The following biochemical events involving low magnesium have been identified in migraine sufferers and may set the stage for a migraine attack: In women who have not yet reached menopause, estrogen rises before the period, causing a shift of blood magnesium into bone and muscle. As a result, magnesium levels in the brain are lowered. When magnesium is low, it is unable to do its job to counteract the clotting action of calcium in the blood. Tiny blood clots are said to clog up brain blood vessels, leading to migraines. Several other substances that help create blood clots are increased when magnesium is too low. Similarly, magnesium inhibits excess platelet aggregation, preventing the formation of tiny clots that can block blood vessels and cause pain. Low brain magnesium promotes neurotransmitter hyperactivity and nerve excitation that can
