I have been using this bone supplement for about 4 years. It was recommended to me by my sister. after using this supplement, we both have reversed our bone loss! I haven't done anything else different - not diet, not exercise, just this bone support. I am a true devotee and have recommended this to several women friends. I had a sports medicine doc incredulous when I told her of my results. She said, "No-one reverses bone loss!" I'm living proof that it can be done!
