Presentation Title:

A compelling scientific rationale for macular carotenoid supplementation in children to support eye and brain health

Abstract

Lutein and zeaxanthin (LZ) are the only carotenoids exclusively deposited in the macula, and preferentially accumulated in the learning and processing regions of the brain. Scientific evidence supports the role for LZ across the lifespan. Dietary intakes LZ are dismally low among adults and supplementation studies have demonstrated benefits for eye health and cognitive outcomes in adults. Dietary intakes are even lower among children with intakes inversely correlated with cognitive performance. Supplementation studies with lutein are missing in children. The goal of our study was to ascertain whether lutein and zeaxanthin supplementation could influence visual and cognitive outcomes in this vulnerable population. Methods: Sixty children, 5-12 years, were supplemented with 12 mg (LZ) or placebo for 180 days. Macular pigment optical density (MPOD) was the primary endpoint. The secondary endpoints included serum levels of LZ, visual processing speed using Critical Fusion Flicker Photometry, and eye strain and fatigue using the Visual-Analog Scale. Additional secondary endpoints involved the Creyos Health (CH) platform to assess attention, focus/concentration, episodic memory and learning, visuospatial working memory, and visuospatial processing speed. Results: The LZ group showed significant increases in serum LZ in parallel with significant increases in MPOD through the study. Visual performance outcomes were favorably influenced by LZ supplementation including reduced eye strain and fatigue as a result of digital device use. Episodic memory and learning, visuospatial working memory, and attention were significantly increased at d90 and d180 of the supplementation period. Conclusions: This is the first clinical study demonstrating LZ supplementation benefits children and corroborates evidence in adults as it relates to eye and brain health, mainly driven by the ability of LZ to increase macular pigment levels. These data are especially relevant given the dismally low intakes of LZ in children, and the wide prevalence of digital device use among children.
