Zeaxanthin Improves Visual Function

FORT LAUDERDALE, Fla.Supplementation with zeaxanthin may improve visual function in older adults with signs of age-related macular degeneration (AMD), according to results of a study presented May 2 at the Association for Research in Vision and Ophthamology (ARVO) 2010 conference here. The Zeaxanthin and Visual Function Study (ZVF) was conducted at the Department of Veteran Affairs Medical Center in North Chicago and sponsored by Chrysantis Inc.

Researchers enrolled 60 older adults with early AMD to participate in the 12-month, double blind, placebo-controlled randomized trial. Subjects who received daily supplementation with zeaxanthin showed increased concentrations in macular pigment as well as a statistically significant improvement in Foveal Shape Discrimination and Kinetic Visual Field under low contrast. In addition, when questioned about specific visual improvements, the zeaxanthin subjects reported a definite improvement in driving performance.

This is the first study that has looked into what is the exact role of zeaxanthin in visual health, said Phil Gowaski, sales and marketing manager for Chrysantis. The results of the clinical trial sponsored by Chrysantis show how zeaxanthin supplementation can influence some of the most basic activities in our every day lives. We anticipate the publication of further studies that corroborate the association between zeaxanthin and the visual functions mostly involved in driving. The range of potential benefits of zeaxanthin in eye health for the general population is truly exciting.
