Zeaxanthin — Uses, Dosage, Side Effects & Safety

Drug class: Carotenoid; Eye Health Supplement

Overview

Zeaxanthin is a naturally occurring carotenoid found in many fruits and vegetables, especially leafy greens and yellow/orange produce. It is commonly used as a dietary supplement to support eye health, particularly for the prevention and management of age-related macular degeneration (AMD) and other retinal disorders. Zeaxanthin works by acting as an antioxidant in the eye, especially in the macula, where it helps filter harmful blue light and neutralize free radicals. This protective effect may help reduce the risk of progression of AMD and support overall visual function. Key points for patients: Zeaxanthin is generally well-tolerated, available over-the-counter, and often combined with other nutrients such as lutein. It should not be used as a substitute for prescribed eye medications. Always consult your healthcare provider before starting any new supplement.
