Which Type and How Much Magnesium for Migraine?

Health Professional

Question:

Hello, Teri and Dr. Watson. I've seen many online conversations about taking magnesium for migraine prevention. In those conversations, many different forms of magnesium are discussed, along with many different dosage levels. I recently discussed this with my doctor, who said it could be a good idea to take magnesium, but he had no idea which form or how much to take. Can you offer any clarification? Thank you for your expertise and time, Maggie.

Answer:

Dear Maggie;

There is a lack of evidence for oral magnesium and migraine prevention to be able to give a good answer to this. In general, magnesium is safe (but one should always consult with their physician first) and its primary side effect is gastrointestinal distress/diarrhea. I personally recommend between 500-1,000 mg per day, divided morning and night, if tolerated. I do not think the type of magnesium makes a huge difference, but if you have side effects with one, trying a different one is reasonable.

Thank you for your question,
Dave Watson
