While some people swear by Glucosamine/Chondroitin supplements, they are declining in popularity as claims of reversal of joint damage and dramatic pain relief from arthritis have been exaggerated. The Mayo Clinic website still lists Glucosamine Sulfate as potentially useful in the treatment of osteoarthritis and it does seem to have some mild anti-inflammatory properties. From what I've read about it over the past few years (I have knee issues due to cumulative injuries) it falls into the "won't hurt, might help" category. Don't expect miracles.
