What this trial studies

This randomized, placebo-controlled crossover trial enrolls adults with macular degeneration and compares 12 weeks of MacuHealth supplementation to 12 weeks of placebo, with each participant receiving both treatments over a six-month period. Skin carotenoid concentration is measured at baseline and during each treatment period to track changes associated with supplementation. Key exclusions include current smokers, pregnancy or breastfeeding, BMI over 30, uncontrolled systemic diseases, and current or prior use of similar supplements. The trial is sponsored by a private eyecare practice in collaboration with MacuHealth and is conducted at a single site in Kansas City.
