Beta-Carotene and Carotenoids
Beta-carotene is best consumed from fruit and vegetable sources, has numerous health benefits, and is a safe way to ensure intake of vitamin A since regular vitamin A intake can be associated with liver toxicity.
Beta-carotene is readily converted to vitamin A in the gastrointestinal tract but will not lead to vitamin A toxicity because lesser amounts of beta-carotene is converted to vitamin A as beta-carotene intake increases.
