Lutein is a major component of the macular pigment in the eye, which filters out harmful high-energy blue light and protects the retina. Higher macular pigment density is associated with better visual performance and reduced glare sensitivity. Lutein is believed to help maintain healthy vision by protecting the eyes from oxidative stress caused by exposure to ultraviolet (UV) light and blue light. It is also believed to have a positive impact on cardiovascular and skin health by reducing inflammation and oxidative stress, which are risk factors for heart disease and skin conditions. HealthAid® Lutein is extracted from marigold flowers.
