Lutein and zeaxanthin consumption ‘improves’ eye performance in the young

The naturally-occurring carotenoids lutein and zeaxanthin can enhance visual performance among young and healthy consumers, according to new research sponsored by two nutritional manufacturers.

The study, from researchers at the University of Georgia, monitored the effect of 10mg of lutein, 2mg of zeaxanthin and a placebo over a one year period. «The results of the study indicate that the regular intake of lutein and zeaxanthin can be beneficial for improving vision in young, healthy people», it concluded.

It noted that serum levels of the two carotenoids and macular pigment optical density, which has been shown to have a major impact on visual performance, increased significantly in the supplemented group. No changes were reported in the placebo group.

The study’s principal investigator said: «The scientific community has known for a long time that increasing macular pigment density can improve many aspects of visual function and the Glare 2 study provides important further confirmation. Showing lutein and zeaxanthin improve function in normal healthy individuals widens its applications, as we continue to investigate the potential of nutrition to support both eye health and visual performance».
