Age-related macular degeneration (AMD) is the leading cause of irreversible vision loss in industrialised countries. This project aimed to assess whether the carotenoids, lutein and zeaxanthin, in comparison to beta-carotene, exert effects on inflammatory markers and oxidative stress that may influence AMD development.

A randomised, double blind, placebo-controlled study in which smokers and non-smokers receive dietary supplements of lutein and zeaxanthin was carried out and various indicators of inflammatory status were monitored over a two-month period. A further study examined delivery of these carotenoids using food supplements (carrot juice for carotene and dried spinach powder for lutein and zeaxanthin).
