Both my functional doc and my regular primary care doc recommended magnesium to me for fibromylagia and chronic fatigue along with migraine headaches. I haven't found the magnesium to directly reduce my migraines, but I know most of us are magnesium deficient, so it's probably still worth considering a supplement.
