FlexiBene is a complex to help relieve joint pain and stiffness in people suffering from arthritis. The chondroprotective effects of glucosamine sulfate (GS), chondroitin sulfate (CS) and undenatured type II collagen (UC-II®) have different molecular mechanisms. Therefore, with the combined oral use of CS, GS and UC-II®, different mechanisms of action of individual components will complement each other, increasing the effectiveness on pain and mobility.
