The osteoporosis topic threads here are also very worthwhile. There is some comparing of supplements that people have found valuable in addition to the standard calcium/D3/K2 recommendations. Some are taking collagen, yet alone 5 kinds (about which I know zip). And a few have added boron to their protocol. I think the coolest thing though is the writers here using vibratory therapy. And it sounds like fun to me too, lol. I'll do anything to not have to watch my inner scaffolding become untrustworthy. I now think of grocery-lugging as weight bearing exercise and resent it less.
