I read recently that there is an {*filter*}calcitonin treatment that has shown
some promise.  Before reading that (I think in an article in *Science
News*), I had heard that calcitonin had been rather disappointing as a
treatment for osteoporosis, and that prevention, namely a good supply of
calcium (childhood through {*filter*}s and during pregnancy and lactation,
especially), and estrogen replacement therapy at menopause were the best
approach to osteoporosis.  Can this or any drug reverse the effects of 20
- something years of bone loss that leads to the fractures of osteoporosis
?

Thanks for any information,
