Chondroitin sulfate is a molecule that is found naturally in the body. It has mostly been used to treat joint disorders, such as osteoarthritis, and problems with the chewing muscles and joints.

Clinical trials on the use of chondroitin for osteoarthritis have found promising results. However, most of the studies are conducted for less than two years. Adequate assessment of long-term safety, side effects, and effectiveness is lacking.

Early evidence suggests that chondroitin sulfate may improve the absorption of iron and measures of coronary artery disease. However, more research is needed in these areas.
