Glucosamine and Osteoarthritis
Supplements are always a bit problematic in terms of figuring out what works and what does not, as the placebo effect is so strong if someone thinks that a substance has a health benefit. As a personal trainer over the past 18 years and working with a lot of individuals with osteoarthritis, I can say that my opinion is mixed. I do not and never do advocate any unproven supplements, but when my clients use something, I take notes to see if there is any validity to the claims. What I saw with 8 clients using glucosamine- some of them used glucosamine with chondroitin, all but one reported an initial sense of relief, but as the months went all of them said symptoms that they had were doing better. (Keep in mind as well that this is just what I saw, the dosages and other control issues were not in any way controlled). The problem with taking this into consideration is that they were all doing supervised resistance training, focused on helping them improve their joint mobility and increasing the strength of their surrounding muscles (6 of the clients had knee issues, 1 had elbow issues and 1 had problems with his fingers).
Was the glucosamine responsible, or was it the training? I am inclined to go with the conclusion that it was the training, as many other clients who did not use any supplements had similar relief over time. What I recommend everyone to use as an authoritative tool in evaluating any supplement claim is the Cochrane Review. They essentially are a well established peer review group that evaluates and confirms the results of thousands of studies in many fields. Their findings were that glucosamine’s effects on humans are thus far questionable at best.
Hope this helps.

Great post, Kevin. Keep the info coming!!!
I used it fir about two year and found it made a bit of a difference
I tried it, nothing happened. I think it just doesn’t work.
I tried glucosamine/chondroitin without much success. I’m now using a brand new product called OmniFlex that has worked very well to eliminate pain & stiffness in my knee.
Never heard of it, but besides being one of those heat type products that temp stop the pain, nothing can really make a joint disorder go away.
I don’t know what your definition of “go away” is, but I no longer have pain or stiffness in a knee that was painful & stiff for years before I started using this product. Hard to believe, but true.
