Magnesium glycinate works for something like 30% of migrane sufferers too. Specifically that one. I wish everyone would specify what formulation with supplements. I.e. vit D, is it cholecalciferol or calcidiol? It matters. Also D2 in mushrooms exposed to the sun, even dried, works, eventually. But rare in supplements!
