Beta carotene 30%
Beta carotene is one of several carotenoids, natural plant pigments found in deeply colored fruits and vegetables. Others include alpha carotene, lutein, lycopene, and zeaxanthin. Beta carotene and some other carotenoids are provitamin A carotenoids, meaning that the body can convert them into vitamin A. Beta carotene is also an antioxidant; thus it may help deactivate free radicals, unstable molecules that are by-products of cells burning oxygen for energy.
