Zeaxanthin is a carotenoid that plays a role in protecting the eyes from the harmful effects of oxidation and light-induced damage. Zeaxanthin is a yellow-colored pigment found in the center of the macula. It is found in high levels in dark green vegetables, orange and yellow fruits, and in the yolk of eggs. In fact, zeaxanthin is the pigment that gives paprika, saffron, and corn their characteristic colors. It is commonly associated with a similar supplement, lutein. Both supplements are carotenoids associated with eye health, found in high levels in many vegetables and fruits.
