Chondroitin Sulfates: A Patient-Friendly Guide
Chondroitin sulfates are sulfated substances found naturally in cartilage and are used mainly to help relieve pain and stiffness from osteoarthritis. They are often taken alone or in combination with glucosamine and other ingredients. Chondroitin may improve symptoms, but it has not been shown to reliably reverse cartilage damage or cure arthritis.
Chondroitin sulfates may provide modest relief of osteoarthritis joint pain and stiffness. Use the dose on the product label, and ask a doctor or pharmacist whether it is safe for you, especially if you take blood thinners or have surgery planned.
