What is ascorbic acid?

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.

Ascorbic acid may also be used for purposes not listed in this medication guide.

Warnings

Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.

Before taking this medicine

You should not use ascorbic acid if you have ever had an allergic reaction to a vitamin C supplement.

Ask a doctor or pharmacist about using ascorbic acid if you have:

  • kidney disease or a history of kidney stones;

  • hereditary iron overload disorder (hematochromatosis); or

  • if you smoke (smoking can make ascorbic acid less effective).

Your dose needs may be different during pregnancy or while you are breast-feeding a baby. Do not use ascorbic acid without your doctor's advice in either case.

How should I take ascorbic acid?

Use exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.

The recommended dietary allowance of vitamin C (ascorbic acid) increases with age. Follow your healthcare provider's instructions. You may also consult the Office of Dietary Supplements of the National Institutes of Health, or the U.S. Department of Agriculture (USDA) Nutrient Database (formerly "Recommended Daily Allowances") listings for more information.
