Lutein belongs to the carotenoid family of antioxidants. Lutein has been found in the eye, brain, breast and cervix. Research has shown lutein to be supportive for vision health. In the eye, it is found mainly in the macular region, as well as the entire retina, ciliary iris bodies and lens. As an antioxidant, lutein Enhances protect macular tissue from photo-oxidation by filtering blue light, and Beneficial Effectss oxidative damage by free radical quenching. Adequate levels of lutein in the eye may potentially be supportive in the absorption and dissipation of damaging UV radiation. Research shows that lutein supplementation can increase serum levels of lutein, and increase macular pigment density.
