Proper joint function

Hyaluronan is necessary for healthy joint function. Because it is abundant in synovial fluid — the viscous fluid found within joints such as knees and shoulders — hyaluronan cushions joints against normal impacts from everyday life*. Hyaluronan forms the infrastructure that other molecules, such as chondroitin sulfate must attach to in order to function normally.* Moreover, hyaluronan serves as a renewal signal to cells in and around the joint so that they synthesize new components to replace those that inevitably wear out due to normal joint stress.* In this way, hyaluronan plays both a structural and a functional role — anchoring critical joint structures while ensuring that new components, critical for proper function, are continually made.*
