This study is looking at how taking a carotenoid supplement affects the health of your retina, which is the light-sensitive tissue at the back of your eye. Researchers want to see if this supplement can improve your macular pigment optical density (MPOD), a protective feature in your eye, and reduce retinal waste. You would take either a carotenoid supplement or a placebo (a pill with no active ingredients) daily for 3 months. To join, you need to be a healthy adult between 18 and 75 years old with good vision and no history of eye or serious health problems. The study will measure changes in your MPOD and a measure of retinal brightness to see if the supplement is successful. The current status of this study is unclear, and it plans to enroll 50 participants.
