Rating (out of 5): 3

Lutein is a carotenoid primarily known for its role in eye health, but emerging research suggests it may also support cognitive function and brain health. Scientific studies have found that lutein accumulates in brain tissue and is associated with cognitive performance across the lifespan. Several observational studies in older adults have correlated higher lutein levels with better memory, processing speed, and executive function. Randomized controlled trials, though limited in number and size, have shown that lutein supplementation can increase serum and brain levels of lutein, and in some cases, improve measures of cognitive function, particularly in older adults or those at risk for cognitive decline.

Mechanistically, lutein is thought to exert neuroprotective effects through its antioxidant and anti-inflammatory properties. It may help protect neural tissue from oxidative stress and inflammation, both of which are implicated in cognitive aging and neurodegenerative diseases. In infants and young children, higher lutein status has also been linked with better visual processing and cognitive development, suggesting a potential role across the lifespan.

However, the overall quality of evidence is moderate: while observational and mechanistic data are promising, large-scale clinical trials are limited, and more research is needed to establish causality and optimal dosing. Thus, scientific support exists, but it is not yet definitive or universally accepted.
