Source Naturals, Lutein, 20 mg, 120 Capsules

Dietary Supplement Antioxidant Carotenoid Lutein is a potent antioxidant carotenoid found in abundance in green leafy vegetables. Lutein is also one of the dominant pigments found in the macular region of the retina of the eye. In the macula, lutein is selectively accumulated from plasma and filters out visible blue light and ultraviolet light. This filtering process serves to protect the retina from photic damage or other oxidative damage.
