Eye vitamins and skin test: a crossover study
Part of Eyes & vision clinical trials.
This study tests whether a supplement containing lutein, zeaxanthin, and meso-zeaxanthin can increase the amount of these nutrients in your skin. You will take the supplement and a placebo at different times to see if there is a difference.

This study tests whether taking daily supplements of lutein, zeaxanthin, and fish oil can improve the protective pigment in your eyes. It may help people with low macular pigment and good vision who are not already taking high doses of these nutrients.
This study tests if taking a carotenoid supplement (MacuHealth) can improve or protect retinal health in healthy adults. You might join if you have normal vision and no major eye or health problems.
This trial tests whether taking carotenoid supplements (like lutein and zeaxanthin) can improve vision. It is for healthy Chinese adults aged 35+ who have good eyesight, no serious eye diseases, and have not taken these supplements recently.
This study measures a pigment in the eye and also looks at other body tissues in people who have a specific inherited eye condition called adult vitelliform dystrophy. It may help researchers better understand the disease and how it can be confused with early age-related macular degeneration.
This trial tests a new way to deliver lutein (a nutrient for eye health) directly into the eye using a gentle electrical current (iontophoresis). It is for people with advanced age-related macular degeneration (AMD) to see if this treatment can help slow vision loss.
This study looks at whether getting (or not getting) xanthophylls—plant nutrients like lutein and zeaxanthin—changes how well you see. It’s aimed at people who are on long-term tube or feeding nutrition and who may be missing these nutrients.
