I have been taking Ultimate Bone Support for MANY years, and have recommended it to anyone I know who has been told they have fragile bones, fortunately only 5 years before I knew about Ultimate Bone Support. When my cataracts were very bad before surgery, and I was having problems with my depth perception and peripheral vision, I took several bad falls, always on something hard. NEVER BROKE A BONE as I had been on the Ultimate Bone Support for several years. I can't say enough positive things about this product and will NEVER be without it!!!
