What is Chondroitin?
Chondroitin is a glycosaminoglycan which is an important constituent of articular cartilage.
Proposed Benefits of Chondroitin
Chondroitin is thought to improve joint health.
Mechanism of Action of Chondroitin
It has been reported that chondroitin may stimulate the production of cartilage, maintain viscosity of joints and inhibit enzymes that degrade cartilage. It is used as an agent to relieve the symptoms of osteoarthritis.
Research on Chondroitin
There have been many clinical trials investigating the effects of chondroitin for the treatment of osteoarthritis. Studies have tended to show a reduction in pain (1-5) and increased mobility (6) with chondroitin supplementation of 800-200mg over periods of 90 days to one year. Chondroitin may be able to influence joint narrowing, but good studies are still lacking in this area.
Rating of Efficacy for Chondroitin
Supplementation with chondroitin appears to improve joint health in individuals with osteoarthritis.
