Lutein is an orange xanthophyll (belongs to the carotenoids family), similar to beta carotene. The main source of lutein is the flowers of Tagetes erecta, a plant particularly widespread in South America. Lutein is contained in the petals of these flowers, and in fact is responsible for the typical coloration.
Lutein has an antioxidant activity as well as being useful for the welfare of eyes.
Indeed lutein (together with its isomer, zeaxanthin) is located in the macula of human eye, the central part of the retina, and is responsible for visual acuity as well as the details of colour contrast and vision. The cells of the retina have a protective effect because they absorb blue light which particularly harmful and to which the human eye is very sensitive.
