A two-group parallel design will be employed whereby participants will be randomly assigned to one of 2 groups. The supplementation doses 20mg/d (Group 1), and placebo (Group 2) will be consumed daily by the participant for a 4-month period. Pre-test and follow-up measures of lutein status and cognitive function will be assessed at baseline and at 4-month follow-up via laboratory visits.
