Vitamin C, also known as Ascorbic Acid, is a vitamin found in food and used as a dietary supplement. Vitamin C is used to prevent or treat low levels of vitamin C in people who do not get enough of the vitamin from their diets. Most people who eat a normal diet do not need extra ascorbic acid. Low levels of vitamin C can result in a condition called scurvy. Ascorbic Acid may also be used for purposes not listed in this medication guide.

How to take Vitamin C. You can buy vitamin C over-the-counter (OTC) in tablet or powder form, in gel tablets, and chewable ones. The recommended dietary allowance of Vitamin C (ascorbic acid) increases with age. Follow your healthcare provider’s instructions. Drink plenty of liquids while you are taking Vitamin C. The chew able tablet must be chewed before you swallow it. Vitamin C gum may be chewed as long as desired and then thrown away.
