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.
