I like that my supplement Thera Cal has it with the calcium, magnesium and Vit D. I hope to see continued improvement or no change next Dexa. I wish I went to the same Dexa machine 2 times ago but I don't know the difference in results that are seen when you change. I went from -2.9 in October to -2.1 June 30th the following year. Can a tech error be that much? I want to think my weightlifting, calcium intake, more protein helped but either way, glad to back in osteopenia and will stick with Yale bone center from now on. I went to Yale satellite time before because of convenience and had no idea it might make results different. What do people do that move?
