Lutein (from the Latin luteus meaning yellow) is one of over 600 known naturally occurring carotenoids. Found in green leafy vegetables such as spinach and kale, lutein is employed by organisms as an antioxidant and for blue light absorption.Lutein is also found in egg yolks, animal fats and the corpus luteum.utein is a xanthophyll, like its sister compound zeaxanthin.
