Hi @smittysmith2, Your wife is fortunate to have you in her corner, and I am sorry for the pain she's experiencing.
In researching osteoporosis, I found Dr. Loren Fishman, who has an ongoing study of selected yoga poses for osteoporosis, which increase bone density. He is on the faculty of Columbia University Medical School. It may be worthwhile to google him, find his interviews, etc.
I don't know anything about Osteostrong, but found this interview with its founder, Dr. John Jaquish with Dr. Doug Lucas, a retired orthopedic surgeon, now speacializing in bone health.

I've often wondered, like you, where the cutting edge research on osteoporosis is being done.
