NCT ID NCT02113254
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether eating corn rich in zeaxanthin (a natural pigment) could increase the density of the macular pigment in the eye, which may help prevent age-related macular degeneration (AMD), a leading cause of blindness. Nine healthy volunteers aged 20-35 ate a daily serving of this corn for 10 weeks. The goal was to measure changes in macular pigment density and blood zeaxanthin levels.
