In brief: Cartilage Components
Glucosamine is a modified sugar that can be crosslinked to form shellfish shells and glycosaminoglyans, a major component of connective tissue.
Chondroitin sulfate is a particular kind of glycosaminoglycan that is especially prevalent in cartilage and is often depleted during osteoarthritis..

In brief: Joint supplements
Many people develop osteoarthritis (wear and tear).
It has been shown that by taking glucosamine and chondroitin supplements joint repair can take place. The book i read on this claimed this regimen helped 50% of the patients.

In large randomized placebo-controlled clinical trials, there has been no proven benefit of cartilaginous healing or extended longevity with the use of any supplements, such as chondroitin or glucosamine. This is an aggressive area of research, given the large amount of expense and pathology associated with DJD.

In brief: Cartilage rebuilder.
The combination of glucosamine and chondroitin has been shown in studies to (1) provide a degree of pain relief in the short term, and (2) trigger growth of new cartilage when taken for at least two years straight.
So it can help you pain and reverse some of the chronic damage. You can find this in the health food store. MSM is not necessary and adds to the cost of the product.
