Lutein, Zeaxanthin, and Meso-Zeaxanthin Supplementation for Macular Degenerative Disease

This study is looking at how a supplement containing Lutein, Zeaxanthin, and Meso-Zeaxanthin affects the amount of carotenoids (natural pigments) in your skin. Researchers want to see if taking this supplement for six months changes these levels. You might be able to join if you are between 18 and 50 years old, don't smoke, are not pregnant or breastfeeding, and don't have certain uncontrolled health conditions like diabetes or heart disease. The study aims to enroll 60 participants. The main goal is to measure your skin carotenoid concentration after six months to see if the supplement has an effect. The current recruitment status is unclear.

Study design
This is a placebo-controlled crossover study, meaning participants will receive both the supplement and a placebo (an inactive substance) at different times. The study plans to enroll 60 participants.
What's involved
Participants will take either the supplement or a placebo for 12 weeks, then switch. Skin carotenoid levels will be measured at 6 months.
Compensation
Not stated in the trial record.
Follow-up
Your skin carotenoid concentration will be measured at 6 months after starting the study.
