I'm a cardio addict and do 250mg liquid Citrate and 200mg of Bisglycinate before sleep. Otherwise restless legs syndrome would kick in badly during the night. Sometimes adding 1.000mg of Gaba also helps with recovery and falling asleep.

Just make sure to stay away from cheap Mg Oxide since bio-availability is somewhere in the 4% range and usually comes in Multi-anything pills.

Someone recommended magnesium to help with my migraines (turns out it was an eye imbalance), so it's been sitting in a drawer but I also have a hard time staying asleep, and am wondering if I should crack it back out. I have some stuff called "Natural Vitality" and it is magnesium carbonate 325mg, does this sound decent to you?

I've never seen Mg Carbonate in a sport supplement but I usually look for the highest bio-availability and the least laxative effect. Hence, Bisglycinate is my best choice. Usually comes in pills and rarely also (expensive) in liquid shots w/ sweeteners.

I've found that the Citrate works best for me. I don't want to quote a brand but it's a well-known brand that's found in every store in my area that sells vitamins as well as online.

If you are still experimenting .... for my RLS, it turned out that B3=Niacin is very helpful, even after onset; And also sufficient iron.

When I take iron in the morning and B3 whenever (morning/day), I don't get RLS.

And important: if you do experiment, I found that only "real" flush-causing B3 works; Not niacinamide/nicotineamide, which apparently has some of the (many) benefits of niacin, though no RLS relief (or flushing). And especially not inositol-hexanicotinate, which I have not found a single reference describing any useful property of (but still gets sold as B3).

I concur with GABA, and for me also sauna works. Mg only together with Ca/D.
