Anecdotal, but I personally would get ocular migraines pretty frequently for years. They started when I was a teenager, but I was always told by doctors that it was nothing to worry about. A few years ago I read about magnesium deficiency and migraines, figured it was worth a shot to try supplementing it, and now I rarely get those ocular migraines. The only time I get them now is when I run out of magnesium supplements, forget to buy more, and end up going a few weeks without them. I really can’t say that it’s the magnesium, but as long as I’m not getting the ocular migraines anymore I’ll continue to supplement it. A bit of a warning though, it can act as a laxative for some people and cause digestive issues. Liquid based forms are gentler. Mineral water tends to have high magnesium content as well (e.g. Gerolsteiner brand).
