While it is present in the walls of blood vessels, chondroitin sulfate’s main role is in keeping cartilage fluid and elastic. It is found naturally in the body where it is one of the critical compounds that makes up connective tissue. Connective tissue is responsible for building and supporting cartilage found in the joints and elsewhere.

There is no dietary source of chondroitin sulfate. As a supplement, it is manufactured from shark, pig, and cow cartilage.

Reported Uses

Because chondroitin is responsible for repair and maintenance of cartilage and connective tissue, it may be of special interest to the elderly. (1) With aging, the water content of cartilage decreases, causing problems with the mobility of joints. Chondroitin may limit the effects of such degeneration.

Chondroitin has been used to treat osteoarthritis. Studies suggest that chondroitin can enhance joint health and lower pain associated with the condition. (2) , (3) Chondroitin may inhibit enzymes that cause inflammation and damage the joints. (4) Other agents that also support joint and cartilage health like glucosamine and manganese are often used along with chondroitin for treatment of osteoarthritis.

The benefits of chondroitin supplementation may carry over to the treatment of joint-related sports injuries (5) and nasal sprays that contain chondroitin may also reduce snoring. (6)
