Lutein and zeaxanthin are carotenoid compounds naturally found in leafy greens, egg yolks, and colorful fruits, though they are often supplemented in concentrated forms derived from marigold flowers. These two compounds are the primary pigments that accumulate in the macula of the eye, where they act as a natural blue light filter and antioxidant shield. Research suggests that adequate intake of lutein and zeaxanthin supports macular health and may help protect against age-related changes in vision, with several studies also indicating potential benefits for cognitive function, including memory and processing speed. Emerging evidence points to a role in skin health as well, where these carotenoids appear to support the skin's natural resilience against oxidative stress from UV exposure. Common supplemental forms include FloraGLO lutein and meso-zeaxanthin, often studied individually or in combination.
