I read that they came up with that 2-1 in favor of Calcium simple going by the make-up of bones and not taking into consideration that you have a lot of magnesium in the muscles and it is needed for nerve transmission and 350 enzematiic functions. From my research and personal experience, I stopped taking supplemental calcium altogether and wouldn't recommend it to anyone who is mercury toxic as hg also blocks mg and you are in need of even more of it to help with detoxification. Also, if you are deficient (and you are if you have hg) in mg and take calcium, your mg deficiency will become even worse because you have to have mg to process calcium. YOur body will even take what it needs from your bones to try and process it.

My mother has osteoporosis and has been on calcium for years and fosomax. She stopped the fosomax and calcium and has only been taking mg (Dr. didn't know) for about 1 1/2-2 years and just had another bone scan done and to his surprise (and I 'm sure dismay because he wanted to try her on his "new" drug) she hadn't lost anyone more bone mass!
