Lutein, also known as "phytolutein", is an oxygen-containing carotenoid that is widely found in natural plants such as marigolds, bananas, kiwis and corns. This compound is an antioxidant with excellent performance, which can resist the damage of cells and organs caused by oxygen free radicals in the human body, and prevent cardiovascular sclerosis, coronary heart disease and tumor diseases caused by aging of the body. Its most important and unique role is that lutein is the only carotenoid component that can exist in the lens of the eye. It is the main pigment and antioxidant component of the retinal macula.
