I am 77 years old, and last year’s DXA showed mild osteoporosis. My Geriatrician agreed with my decision to avoid medication. I am in good health and take only one medication. My 13 year old grandson told me about Collagen Peptides. I looked up the research, and started on a good brand 3 weeks ago. I have very little arthritis, but it should also be good for joints, where collagen is lost.
