Vitamin C

Vitamin C, also known as ascorbic acid, is a water-soluble vitamin which is essential for normal functioning of the body. Unlike most mammals, humans don't have the ability to make their own vitamin C. We must therefore obtain vitamin C through our diet. It is essential in wound healing and in the formation of collagen, a protein important in the formation of healthy skin, tendons, bones, and supportive tissues. Deficiency results in defective collagen formation and is marked by joint pains, irritability, growth retardation, anemia, shortness of breath, and increased susceptibility to infection.
