Actually, you know what, I think you're on to something. Had my second vitamin D dose Saturday and the cramps/spasms have come back with a vengeance. Apparently vitamin D supplementation can cause you to lose magnesium (it's used for converting different forms of D in the body or something). I took significantly more than I was (turned out I was only taking about 100mg per day, I misread the bottle) and it seems like it's helping so far.
