Vitamin C, also known as L-ascorbic acid, is a powerful antioxidant, playing a major role in immune and joint health1.* It’s also a co-factor in the process of collagen synthesis, the main protein in joint tissues and bones2.*
Two enzymes are required for the collagen synthesis: prolyl hydroxylase and lysyl hydroxylase. Together with vitamin C, they define the strength of the joints’ tissue3.*
