What is chondroitin sulfate?
Chondroitin sulfate is important for healthy joints. It is one of the components of the tissue that covers the surfaces of the bones in your joints (i.e., knee, elbow, hip), called articular cartilage. Chondroitin sulfate helps make up a portion of the tissue covering the bones in the joint that function as a type of shock-absorber for the joint.
