Vitamin A And Beta-carotene

Vitamin A is an essential fat-soluble vitamin, while beta-carotene is a provitamin A carotenoid, meaning the body can convert it into Vitamin A. Both are found naturally in various fruits, vegetables (like carrots, sweet potatoes, and dark leafy greens), and animal products such as liver and dairy. They can also be produced synthetically for use in fortified foods and supplements.

Manufacturers add Vitamin A and beta-carotene to foods primarily as nutrients to prevent deficiencies and support overall health. Beta-carotene also serves as a natural yellow-to-orange colorant in many food products. They are commonly found in fortified dairy products, cereals, margarine, and baked goods.

Vitamin A and beta-carotene are essential nutrients. The FDA generally recognizes both as safe (GRAS) when used appropriately in food. Vitamin A is crucial for vision, immune function, and cell growth. Beta-carotene is a provitamin A carotenoid, meaning the body converts it to Vitamin A, and it also acts as an antioxidant. JECFA and EFSA have evaluated both Vitamin A and beta-carotene and have set acceptable daily intakes. While high intakes of preformed Vitamin A can be harmful, high doses of beta-carotene are generally considered safe, though they can cause temporary yellowing of the skin. Some studies have indicated a potential increased risk of lung cancer in smokers who take high-dose beta-carotene supplements.
