Even JAMA admits glucosamine is effective against osteoarthritic pain.
A 2000 study (1) published in the Journal of the American Medical Association (JAMA) showed that glucosamine and chondroitin, 2 food supplements, do appear to help with symptoms of osteoarthritis. The authors of the study analyzed 15 previously published studies on the effects of glucosamine and chondroitin on osteoarthritis.

The findings of the study, adjusted for variability and quality in the supplements, showed a significant benefit from glucosamine supplements as well as from chondroitin supplements.
In March 2000, the study in the Journal of the American Medical Association (JAMA) concluded:
"Trials of glucosamine and chondroitin preparations for osteoarthritis symptoms demonstrate moderate to large effects, but quality issues and likely publication bias suggest that these effects are exaggerated. Nevertheless, some degree of efficacy appears probable for these preparations." (1)
