Beta-carotene belongs to a group of colored pigments called carotenoids. It's converted to vitamin A in the body and found in many fruits and vegetables.

Beta-carotene and other red, orange, and yellow pigments called carotenoids are considered antioxidants. They provide about 50% of the vitamin A needed in the diet. Vitamin A is an essential nutrient. Its antioxidant and anti-inflammatory effects help to protect cells from damage.

People use beta-carotene for an inherited disorder marked by sensitivity to light. It is also used to prevent certain cancers, heart disease, cataracts, aging skin, and many other purposes.
