Vitamin C, also known as L-ascorbic acid, is a water-soluble vitamin that is naturally present in some foods, added to others, and available as a dietary supplement. Humans, unlike most animals, are unable to synthesize vitamin C endogenously, so it is an essential dietary component. Vitamin C is required for the biosynthesis of collagen and certain neurotransmitters. Collagen is an essential component of connective tissue- a structural component of cartilage, ligament, tendons, blood vessels, and skin.
