While it is true that lutein and zeaxanthin are naturally stored in the macula of healthy eyes, the body cannot produce its own lutein or zeaxanthin.

While these carotenoids are found in a variety of foods such as leafy green vegetables, peppers, mangoes, and egg yolks, many Americans still do not get enough of these important nutrients through diet alone for optimal eye health.*
