Early Childhood Lutein and Zeaxanthin Intake is Positively Associated with Early Childhood Receptive Vocabulary and Mid-childhood Executive Function but no Other Cognitive or Behavioral Outcomes in Project Viva.

The overall findings do not provide strong evidence of an association between child L/Z intake and cognition and behavior. However, the positive associations found between early childhood L/Z intake and early childhood receptive vocabulary and mid-childhood executive function, in addition to previous evidence of neurodevelopmental benefit of L/Z intake, suggest that this relationship deserves further investigation.
