How it works
Provides antioxidant protection and supports neural efficiency, especially in visual processing.
Overview
Lutein is best known for its role in eye health, but it also accumulates in brain tissue where it may support cognitive function and processing speed. Its effects are subtle and long-term, focusing on protection against age-related decline rather than immediate cognitive enhancement. It is often paired with other carotenoids for synergistic benefits.
