After researching several of those bone supplements and talking to my rheumatologist, I feel like these companies are just trying to get your money and also they don’t have the correct amount of calcium and vitamin d that I need so I would have to supplement and they are very pricey. I am going to be seeing an endocrinologist to see if he can tell me anything different than my rheumatologist and go from there . I am currently just on 1200 mg of calcium and 2000 IU of Vitamin D.
