The Three Macular Carotenoids: Complementary Functions of Lutein, Zeaxanthin and Meso-Zeaxanthin

JAMES STRINGHAM

Lutein and the two zeaxanthin isomers, RR-zeaxanthin (3R,3’R-zeaxanthin) and meso-zeaxanthin (3R,3’S-RS-zeaxanthin) are the only three carotenoids found in the eye, specifically in the macula of the retina (Bone et al. 1997).

The layer of the macula that is the outermost shield, and first line of defense from environmental and oxidative stress is comprised of pigments Lutein, Zeaxanthin (and… More →
