Effects of Xanthophylls on Optical Density

NCT01316198 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 20

Last updated 2012-07-27

No results posted yet for this study

Summary

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.

Conditions

  • Age-Related Macular Degeneration

Verum

10 subjects consume for 4 weeks a beverage containing 10 mg lutein and 3 mg zeaxanthin per day

DIETARY_SUPPLEMENT
