First of all thanks a million for all your advice on Biphosphonates I think I am going to try some other methods of improving my bone health before I go down the Biphosphonate route. I think the reason they have been recommended to me eventhough I am not in the osteoporosis range just yet (T-2.3) is that I broke my wrist recently and this adds an extra dimension to the whole thing.
I have another question. Have any of you tried rebounding (mini trampoline!) as a means of improving bone health? My research seems to suggest that it could be a good option for me and I was just wondering if any of you had tried it?
