This is a yellow pigment created by plants that is absorbed and used by animals. Lutein is found in animal fats and is what gives egg yolks that yellow color. It is found in the retina along with another similar pigment called zeaxanthin. Lutein and zeaxanthin supplementation has been studied and found to be beneficial with macular degeneration (see the AREDS 2 Study for more information on this topic).
