I had a spate of migraines last week and went to both the doc and chirpractor. Both of them recommended taking 500mgs of magnesium a day. Spoke to chiropractor again this morning and he said that both he and the doc were at the same seminar here in Hungary in March and a headache specialist from the States was speaking at it and he recommended the magnesium supplements. They have both recommended it to patients with good results.
So just thought I would pass it on as it is not something I have heard of before.
