Joint Function Improvement

Joint fluid and articular cartilage contain hyaluronic acid at high concentration. It serves as a lubricant (preventing bone-to-bone friction) and as a cushion. This function allows our joints to move smoothly.

Treatment

A common medical treatment uses HA as a joint function improving agent. HA is injected into joints to treat patients suffering from knee osteoarthritis, periarthritis of the shoulder and knee pain from rheumatoid arthritis. HA has been reported to have anti-inflammatory and pain relieving effects in such uses.
