Hyaluron 100 with high molecular weight hyaluronic acid for an active life and a high-performing body. Hyaluronic acid naturally occurs in the body's joints and gives the joint fluid its shock-absorbing properties, allowing the joint surfaces to glide more easily against each other. Additionally, hyaluronic acid supplies the cartilage with nutrients and oxygen to create the right conditions for the joints. It is found in the knees, elbows, and fingers, among other places. Hyaluronic acid enables the body to move normally and lead an active life.
