Lutein belongs to the carotenoid family of antioxidants. In the body 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, the entire retina, ciliary iris bodies and lens. As an antioxidant, lutein supports the body in protecting macular tissue from photo-oxidation by filtering blue light and preventing 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 involving lutein supplementation has shown a 130% increase in serum levels of lutein. Furthermore, most subjects had an increase in their macular pigment density as a result of the supplementation.
