Study Summary

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.

Study Description

Macular degeneration, cognitive decline, and osteoporosis often occur with aging. Lutein, zeaxanthin, and fish oil (LZF) have been shown to have improvements in these areas. This 6-month double-blind randomized controlled trial will study the impact of LZF on cognitive performance, macular pigment optical density (MPOD), and bone health in healthy adults ages 18-45 with a MPOD <.43. We seek to create a precision nutrition model reducing macular degeneration, cognition, and bone health that includes non-invasive screening for high-risk carotenoid deficiencies (MPOD, dietary intake) and individual response to LZF supplementation.

Healthy adults ages 18-45 years with MPOD <.43 will be randomly assigned to take a LZF supplement with 7 mg lutein, 14 mg zeaxanthin, and 245 mg fish oil or a placebo daily for six months. They will have baseline and ending measures of fasting blood draw, MPOD, bone health using a DXA, and visual cognitive performance using Neurotracker software.
