Zeaxanthin
Overview
Zeaxanthin (C40H56O2) is a xanthophyll carotenoid that concentrates in the central fovea of the macula lutea and functions as a selective blue-light absorber (400–500 nm) and free-radical quencher. Clinical evidence from AREDS2 and multiple RCTs supports 2–10 mg daily (combined with lutein) for reducing progression to advanced age-related macular degeneration. Almost always sold paired with Lutein — both compete for the same carotenoid transport pathway; combined supplementation is preferred. Fat-soluble: requires dietary fat for absorption. No significant drug interactions; excellent safety profile at supplemental doses.
