My neurologist has suggested I try taking a magnesium supplement in addition to 200mg of metoprolol daily to try to better manage my migraines. I know there's so many different supplement companies and they're not all the same quality. Anyone know of any particular brands of magnesium that are better than any others when taking for migraine management? And anyone know if any particular types are better than any others (magnesium oxide, magnesium citrate, etc.)
