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.

Macular Pigment Optical Density (MPOD)
Timeframe: MPOD will be measured at baseline, 3 months after the start of the study, and at the final 6 month visit, which will be the completion of the study.
Cognitive Performance
Timeframe: Cognitive performance will be measured at the three baseline appointments, the three appointments at 3 months, and the 3 appointments at 6 months after the start of the study, which will be the completion of the study
Bone Density
Timeframe: Bone density will be measured at baseline and at the final 6 month visit, which will be the completion of the study.
