Hi, @lamd, I just had a bone density done last week. They measured my spine and wrist (they can't do my hip because I have fractured both of them). Anyway, results were a mixed bag. Very happy that spine density increased by 10.4%! However wrist decreased by about the same amount, so go figure! I must say that I also started strength exercises, just dumbells at home, and have made huge changes to my diet. I will continue with the collagen pep as I had no side effects at all. I have tried a couple of other fortibone products and find dr Mccormick's to be the best. Best of luck to you!
