What is vitamin A?
Vitamin A is an essential nutrient that supports skin, eye, reproductive health, and immune function. There are two types of vitamin A: retinoids (preformed vitamin A) and carotenoids (preformed vitamin A). Both types are converted to retinol by the liver. Vitamin A is a fat-soluble vitamin, and its different forms are often called "retinoids." They include retinol, retinal, retinoic acid, and retinyl ester. Vitamin A is needed for the proper growth and functioning of many body parts, including the eyes, skin, and immune system. It is found in many foods, including fruits, vegetables, and fish. Carotenoids are a group of chemicals found in plants, and some can be converted to vitamin A in the body. People most commonly use vitamin A for treating vitamin A deficiency, and it is also used for aging skin, acne, HIV/AIDS, cataracts, child development, infections, and many other conditions.Vitamin A in foods
