Chondroitin sulfate is naturally found in the connective tissue of joints. Its special structure attracts water, which promotes water retention within the connective tissue.* This water retention is helpful because it supports joint flexibility and cushion the joints.* Chondroitin also works with enzymes involved in cartilage maintenance.* Enzymes are substances that help to carry out a specific reaction. The way chondroitin interacts with these enzymes helps to maintain a healthy balance to maintain cartilage health.*
