Macular lutein and zeaxanthin are related to brain lutein and zeaxanthin in primates [PDF]

Nutritional Neuroscience, 2013
Xanthophyll pigments lutein and zeaxanthin cross the blood-retina barrier to preferentially accumulate in the macular region of the neural retina. There they form macular pigment, protecting the retina from blue light damage and oxidative stress. Lutein and zeaxanthin also accumulate in brain tissue.

Lutein, Zeaxanthin and Meso-zeaxanthin Supplementation Associated with Macular Pigment Optical Density

Nutrients, 2016
The purpose of this study was to evaluate the effects of lutein, zeaxanthin and meso-zeaxanthin on macular pigment optical density (MPOD) in randomized controlled trials (RCTs) among patients with age-related macular degeneration (AMD) and healthy subjects.

Zeaxanthin: Metabolism, Properties, and Antioxidant Protection of Eyes, Heart, Liver, and Skin

Antioxidants, 2019
Zeaxanthin, a non-provitamin A carotenoid that belongs to the xanthophyll family, has been less studied than its isomer lutein. However, zeaxanthin has also been shown to have a number of beneficial effects for human health due to its ability to quench ...

Dietary Carotenoids and Cognitive Decline: A Longitudinal Study Among Chinese Middle-Aged and Older Adults. [PDF]

Health Care Sci
Higher intake of dietary carotenoids was associated with slower cognitive decline. The strongest protective association was observed for moderate carotenoid intake. Total carotenoid intake exhibited a non‐linear association with cognitive decline. ABSTRACT Background This study examined the association between dietary intakes of total and specific ...

Carotenoid-Rich Pigment Extract From Micrococcus terreus SK34 Induces Apoptosis in SH-SY5Y Neuroblastoma Cells: Integrated Metabolomic, Molecular Docking, and Experimental Validation. [PDF]

Microbiologyopen
Carotenoid extract from Micrococcus terreus SK34 was characterized by LC‐Q‐TOF‐MS and evaluated for its in vitro anticancer potential. The extract exhibited selective cytotoxicity against different cancer cell lines, particularly neuroblastoma cells (SH‐SY5Y), while sparing normal cells.

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

Journal 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 ...

Plasma lutein and zeaxanthin concentrations associated with musculoskeletal health and incident frailty in The Irish Longitudinal Study on Ageing (TILDA)

Experimental Gerontology, 2023
Introduction: Lutein and zeaxanthin are diet-derived carotenoids that are proposed to help mitigate frailty risk and age-related declines in musculoskeletal health via their anti-oxidant and anti-inflammatory properties.

The effect of modified eggs and an egg-yolk based beverage on serum lutein and zeaxanthin concentrations and macular pigment optical density: results from a randomized trial.

PLoS ONE, 2014
UnlabelledIncreasing evidence suggests a beneficial effect of lutein and zeaxanthin on the progression of age-related macular degeneration. The aim of this study was to investigate the effect of lutein or zeaxanthin enriched eggs or a lutein enriched egg-

The generation of metabolic changes for the production of high-purity zeaxanthin mediated by CRISPR-Cas9 in Chlamydomonas reinhardtii

Microbial Cell Factories, 2020
Background Zeaxanthin, a major xanthophyll pigment, has a significant role as a retinal pigment and antioxidant. Because zeaxanthin helps to prevent age-related macular degeneration, its commercial use in personalized nutritional and pharmaceutical ...
