Lutein By Xi'an Lvsen Biotechnology Co.,ltd

These Lutein is one of over 600 known naturally occurring carotenoids. Found in green leafy vegetables such as spinach and kale. Lutein is present in the plant as fatty-acid ester, with one or two fatty acids bound to the two hydroxyl-groups. Saponification of lutein esters yields lutein in approximately a 2:1 weight-to-weight conversion.
