I went to a new rheumatologist this past week. He told me I was taking the wrong magnesium I have been using Natural Calm powdered magnesium for about a year now. I can't remember if it has magenisum gluconate or citrate, but it fizzes when you mix it with water. I usually buy the huge bottle, dump it into a container and measure out two teaspoons, so I threw out the bottle and couldn't remember which type of magnesium it is. Well, I told him I take it for sleeping, but I could only take two teaspoons or else it would give me really bad diarrhea. He wants me to take Nature Bounty magnesium oxide at 500 milligrams per day. I was getting about 400 with the other magnesium. At first I thought, a cheap magnesium like this is a waste of my time, although not my money, it really is cheap, only $5.99 for 100 caplets compared with my Natural Calm which cost me about $32.00 for a 4 month supply. I told him I was sensitive to supplements as well, and he convinced me to take 250 milligrams during the day, then another 250 milligrams about 2 hours before I go to bed, so that is what I did. This works. Couldn't believe it. I feel less achey, I was able to go to sleep, it gives me energy, yet calms me enough for sleeping. I hope this isn't a fluke or something, but it has helped with pain and muscle tightness better than the Natural Calm did. He also wants me to continue with my CoQ10 at 200 milligrams. He took another Vitamin D test, a blood magnesium serum test, and a test for phosphorus. He didn't say much else for now, but to see him again in 2 months. He was older, hard to understand sometimes, but gave me a thorough exam. He also told me that I am double jointed and was pre-disposed to having FM, not sure what he meant by that, I didn't ask at the time, I was actually having some brain fog going on, and getting my words out was difficult for me that day. I always thought magnesium oxide was not all that great, but maybe different forms work for different people, who knows, I just hope the better feeling lasts. The only thing I didn't like about the visit was that he focused a lot on my muscles, but didn't say much about brain fog, or he seemed to not be too interested in that right now. Hugs, Chelz.
