About

The objective of the study was to investigate the influence of a intervention with lutein und zeaxanthin from crucifers on the optical density of the macular pigment of patients with non exudative age-related maculopathy. It is hypothesized that the applied study beverage elevates plasma concentrations of the administered xanthophylls and the optical density after 4 weeks of intervention.
