Research Summary
Clinical trials, including the AREDS2 study, demonstrate zeaxanthin's role in reducing advanced age-related macular degeneration risk when combined with lutein and other antioxidants. Research shows zeaxanthin accumulates selectively in the macula and protects photoreceptors from blue light-induced oxidative stress. Evidence suggests supplementation is most beneficial for individuals at genetic risk or with early signs of macular disease.
