Increased intake of zeaxanthin-rich foods to increase plasma zeaxanthin concentration
Zeaxanthin is an oxygenated carotenoid, and a structural isomer of lutein. Both zeaxanthin and lutein are
concentrated in the fovea, or ‘yellow spot’, of the eye, and constitute the macular pigment. In humans, zeaxanthin is
located primarily in the central area of the macula, and lutein is found more peripherally.
