BioCell Collagen is the only hydrolyzed collagen that provides collagen and also substantial amounts of glycosaminoglycans (GAGs) such as hyaluronic acid (HA) and chondroitin sulfate, all in remarkably bioavailable forms. Type II collagen is a predominant type of collagen in articular cartilage. 2  Hydrolyzed form is also effective in reducing UV damage in the skin (Tanaka et al, 2009, Biotechnol Biochem). 3  Essential components both for the joint and the skin.
