Lutein, Zeaxanthin, andmeso-Zeaxanthin in the Clinical Management of Eye Disease [PDF]

open access: yesJournal of Ophthalmology, 2015
Lutein, zeaxanthin, andmeso-zeaxanthin are xanthophyll carotenoids found within the retina and throughout the visual system. The retina is one of the most metabolically active tissues in the body. The highest concentration of xanthophylls is found within the retina, and this selective presence has generated many theories regarding their role in ...

A Brief Overview of Dietary Zeaxanthin Occurrence and Bioaccessibility

open access: yesMolecules, 2020
As it exhibits no provitamin A activity, the dietary intake of zeaxanthin is not considered essential. However, its contribution to ocular health has long been acknowledged. Numerous publications emphasize the importance of zeaxanthin alongside lutein in

Macular pigment response to a supplement containing meso-zeaxanthin, lutein and zeaxanthin [PDF]

open access: yesNutrition & Metabolism, 2007
Age-related macular degeneration (AMD) is a disease with multiple risk factors, many of which appear to involve oxidative stress. Macular pigment, with its antioxidant and light-screening properties, is thought to be protective against AMD. A result has been the appearance of dietary supplements containing the macular carotenoids, lutein and zeaxanthin.
