Patient Education

Vitamin A


Vitamin A is used as a dietary supplement when the amount of vitamin A in the diet is not enough. People most at risk for vitamin A deficiency are those with a limited variety of food in their diet and in those with cystic fibrosis (an inborn disease that causes problems with breathing, digestion, and reproduction) and malabsorption problems (problems absorbing food). Vitamin A is used to prevent and treat xerophthalmia (unable to see in low light) and night blindness. Vitamin A is in a class of medications called an antioxidant. It is needed by the body to help with vision, reproduction, cell growth, and to support the immune system. It works to protect your cells against free radicals and to support cell growth and function.
