ZeaxanthinLutein and Zeaxanthin are carotenoids found in highest concentration in the macular region of the eyes (the back of the eye where the retina is located). Like other carotenoids, Lutein and Zeaxanthin act as antioxidants, protecting cells against the damaging effects of free radicals. They also act as filters against the oxidizing ultraviolet light of the sun in light-sensitive tissues, such as the macula, lens, and retina. Food sources of Lutein and Zeaxanthin include corn, egg yolk, green vegetables, such as broccoli, green peas, brussel sprouts, cabbage, kale, collard greens, spinach, lettuce, and fruits, including kiwi and honeydew melon. Zeaxanthin is the principal pigment in yellow corn. Lutein and Zeaxanthin have identical chemical formulas and are isomers.
