Ascorbic acid (vitamin C) occurs naturally in foods such as citrus fruit, tomatoes, potatoes, and
leafy vegetables. Ascorbic acid 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.
Ascorbic acid may also be used for other purposes not listed in this medication guide.
