Thanks so much for sharing your experience with Strontium Citrate! That's very encouraging. I just started taking AlgaeCal and AlgaeCal Booster (their Strontium Citrate). Unfortunately, as a breast cancer survivor, my oncologist strongly advised me not to take HRT. I wonder if my AlgaeCal supplements, along with protein supplements, and weight-bearing exercise, will give me an impact similar to yours (?). I am 72 and fortunately have not experienced any fractures. While my DEXA scan results are bad (and have not been helped by years of being on Fosamax), my REMS scan results show that my hips and spine are quite strong, especially for my age. My fragility score for the hips shows a 3% chance of a fracture in the next five years. For my spine, my fragility score shows a 6-10% chance (not as good as my hips). Dr Andy Bush (who did the REMS scan) recommended HRT (as did my gynecologist), but as I mentioned above, my oncologist vetoed it.
