How does it work?

Most of the beneficial effects of xanthophylls, such as lutein, zeaxanthin, and meso-zeaxanthin, are ascribed to their ability to quench reactive oxygen species and scavenge other free radical substances that are either taken in from the environment or generated internally by natural metabolic processes. There is evidence for the free radical scavenging activity of lutein is in studies of its effects on human lens epithelial cells. In one such study, cell cultures were exposed to ultraviolet (UV) light after pretreatment with lutein or alpha-tocopherol. Both nutrients were found to reduce UV-induced damage to lens epithelial cells. However, lutein was shown to have significantly higher photoprotective activity than alpha-tocopherol, demonstrating its potential as a high-powered antioxidant. Lutein has also been found to be an effective filter of “blue light,” another daily source of oxidative stress on the polyunsaturated fatty acid-enriched photoreceptors of our eyes.
