Vitamin C, also called L-ascorbic acid, is a water-soluble vitamin that naturally resides in some foods and is added to others. This vitamin is also available to individuals as a dietary supplement. Unlike most animals, humans cannot synthesize vitamin C endogenously; therefore, it is an essential nutritional component.
