Magnesium is effective in preventing migraine headaches according to a new study published in the last issue of journal Magnesium Research. The researchers found that patients treated with magnesium, compared to those treated with placebo, had fewer migraine attacks and the attacks were milder. In addition, magnesium treated patients had improved blood flow in their brains, while those on placebo did not. This is just another confirmation of previous findings of the efficacy of magnesium in the treatment of migraine headaches. Since magnesium is very inexpensive and extremely safe, every patient with migraine headache should be given a trial of magnesium supplementation.
