Clinical Trial Summary

The central hypothesis is that lutein supplementation will improve MPOD and cognition. Accordingly, the specific aims are to 1) to determine the process feasibility associated with participating in 4-month lutein supplementation trial; and 2) to investigate the scientific feasibility of 4-month daily lutein supplementation on biological markers of lutein status and cognitive function among persons with MS.

Description:

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.
