• "Vitamin C, a vitamin that occurs naturally in fresh fruits, esp. citrus, and vegetables, and can also be synthesized. It is essential in maintenance of collagen formation, osteoid tissue of bones, and formation and maintenance of dentin. This essential vitamin is used as a dietary supplement and in the prevention and treatment of scurvy. Scurvy develops after approx. 3 mo. of ascorbic acid deficiency in the diet. The usefulness of large daily doses (1 to 5 g or more a day) of this vitamin in preventing or treating the common cold in otherwise healthy persons has not been established although it may decrease the severity of symptoms. Continuous treatment with large doses can cause kidney stones." 1
