The main reason for my bone loss is estrogen loss. It takes a whole body approach to find the cause and turn it around. I should have been put on HRT at the time of menopause. I am on HRT now. My OBGYN wanted to put me on meds when I had osteopenia. I deferred until it went osteoporosis. When I did not see a reverse after 2 years of meds my OB said "Oh, Big Pharma just wants to sell their product". So she knew but still pushed to put me on it. Anyway, I am at a good place now and going natural.
