1. See my references, I believe the NIH GAIT study is the best, here are others specifically covering Cosamin DS.

There are many other studies involving FCHG49® Glucosamine HCL and TRH 122® LMW Chondroitin Sulfate in the literature including the most recent NIH study. These are the same materials used in Cosamin DS. These appear in CORR , Clinical Orthopedics and Related Research, Experimental Biology and Medicine, Osteoarthritis and Cartilage, Proceedings, AAOS ( American Academy of Orthopedic Surgeons) 68 th Annual Meeting 2001, Clinical Rheumatology, Journal of the American Medical Association and Journal of Rheumatology. For those of you not in the medical field, these are quite respected journals.
