Beta-Carotene 1 article

Orange pigmentation and provitamin A activity distinguish beta-carotene within the carotenoid family. Its role differs from lycopene, which is a carotenoid without provitamin A activity, so a food's carotenoid content and its vitamin A contribution should not be treated as the same measurement. Carrots, sweet potatoes, pumpkin, and dark leafy greens are familiar food sources, and beta-carotene may also be used in fortified foods or supplements.
