Lutein and Zeaxanthin

Two carotenoids, lutein (pronounced loo-teen) and zeaxanthin (pronounced zee-uh-zan-thin), are antioxidants that are located in the eye. Green leafy vegetables, as well as other foods such as eggs, contain these important nutrients. Many studies have shown that lutein and zeaxanthin reduce the risk of chronic eye diseases, including Age-related Macular Degeneration (AMD) and cataracts.

Benefits to Eye Health:Lutein and zeaxanthin filter harmful high-energy blue wavelengths of light and help protect and maintain healthy cells in the eyes. Of the 600 carotenoids found in nature, only these two are deposited in high quantities in the retina (macula) of the eye.

The best natural food sources of lutein and zeaxanthin are green leafy vegetables and other green or yellow vegetables. Among these, cooked kale and cooked spinach top the list, according to the U.S. Department of Agriculture (USDA).

If you are not getting enough lutein and zeaxanthin through your diet alone, consider taking daily supplements. Although there is no recommended daily intake for lutein and zeaxanthin, most recent studies show health benefits in taking 10 mg/day of a lutein supplement and 2 mg/day of a zeaxanthin supplement.
