So I forgot about "smiling n nodding". Dont beat me up. My D is 134. I got a lecture about D toxicity. But its right where I want it. I am trying to reverse osteopenia. Except latest DEXA shows severe osteoporosis within one year. High risk of fracture. My PTH is 27. It was higher, thanks to my experiment with Jarrow Bone-Up, which I deem a failure. I am back on calcium citrate, with carbonate mixed in. My MD is pushing drugs for bone building. What I need from my DS peeps is personal experience with bisphos-whatevers, and any other osteoclast inhibitors. I am also suspicious of these results, as I am rather petite at 5'2" and 120lbs (before pooping). I know, TMI. It is possible my bone density is normal for my size, I have learned from a week of research.
