What the study is about

The goal of this clinical trial is to learn the impact of lutein, zeaxanthin, and fish oil (LZF) supplementation in healthy adults.

The main question it aims to answer is: Will supplementation with LZF improve macular pigment optical density (MPOD), cognitive performance and bone mass compared to controls after six months?

Subjects with an MPOD \<.43 will significantly improve MPOD after 6-months of LZF supplementation.

Consuming a LZFO supplement for 6-months will improve visual cognitive performance. Consuming a LZFO supplement for 6-months will improve bone density.

Participants will be asked to take either a LZF supplement or placebo daily for 6 months.

Being studied: Active Comparator (Lutein, zeaxanthin, and fish oil supplement (LZF); Placebo Comparator

Conditions: Cognitive Performance; Age-Related Macular Degeneration; Bone Loss
