Yes, reduce fractures. Some of the drugs are better at that then others, but the % of reduction is small when you read the studies. The truth is the drugs make your bones more brittle in the the long term. Also, it is designed to keep you on the drugs for life because the studies are only done up to 2-3 years. That is why they take you off and put you on different ones. More people fracture with osteopenia than osteoporosis because there is more of THEM. I say we have freedom in this country to make our own decisions but we must be an advocate for our own healthcare and do our own research.
