Vitamin A is a fat-soluble vitamin. 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 parts of the body, including the eyes, skin, and immune system. It can be found in many foods, including fruits, vegetables, and fish. Carotenoids are a group of chemicals found in plants. Some can be converted to vitamin A in the body.
People most commonly use vitamin A for treating vitamin A deficiency. It is also used for aging skin, acne, HIV/AIDS, cataracts, child development, infections, and many other conditions.
