Ascorbic acid (vitamin C) occurs naturally in foods such as citrus fruit, tomatoes, potatoes, and leafy vegetables. Vitamin C is important for bones and connective tissues, muscles, and blood vessels. Vitamin C also helps the body absorb iron, which is needed for red blood cell production.
Ascorbic acid is used to treat and prevent vitamin C deficiency.
