Analysis of Lutein, Zeaxanthin, and Meso-Zeaxanthin in the Organs of Carotenoid-Supplemented Chickens [PDF]
Foods, 2018 The macular carotenoids (i.e., lutein (L), zeaxanthin (Z) and meso-zeaxanthin (MZ)) exhibit anti-inflammatory, antioxidant and optical properties that are believed to support human health and function. Studying the accumulation and distribution of these nutrients in tissues and organs, in addition to the eye, is an important step in understanding how ...

A Brief Overview of Dietary Zeaxanthin Occurrence and Bioaccessibility
Molecules, 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]
Nutrition & 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.

Effects of Zeaxanthin on Growth and Invasion of Human Uveal Melanoma in Nude Mouse Model
Journal of Ophthalmology, 2015 Uveal melanoma cells were inoculated into the choroid of nude mice and treated with or without intraocular injection of zeaxanthin. After 21 days, mice were sacrificed and the eyes enucleated.

Factors Differentiating the Antioxidant Activity of Macular Xanthophylls in the Human Eye Retina
Antioxidants, 2021 Macular xanthophylls, which are absorbed from the human diet, accumulate in high concentrations in the human retina, where they efficiently protect against oxidative stress that may lead to retinal damage.
