Vitamins Lutein and Zeaxanthin
Lutein and zeaxanthin are part of the carotenoid family, a group of beneficial compounds synthesized by plants.
Both of these carotenoids can be found in the macula and retina of your eyes, where they help filter potentially harmful blue light, thus protecting your eyes from damage (28Trusted Source).
Several studies suggest that these plant compounds may prevent cataracts and prevent or slow the progression of AMD (29Trusted Source, 30Trusted Source).
A randomized, controlled study found potential benefits of lutein for people with cataracts. Over two years, those taking supplements containing 15 mg of lutein three times per week experienced improvements in vision (31Trusted Source).
Recommended daily intakes and safe supplemental doses have not been established for these compounds. However, up to 20 mg of lutein per day for 6 months has been used in studies without adverse effects (32).
Nonetheless, supplements may not be necessary. As little as 6 mg of lutein and zeaxanthin may yield benefits, and a diet rich in fruits and vegetables naturally provides this amount. Cooked spinach, kale and collard greens are particularly high in these carotenoids (32).
Lutein and zeaxanthin are beneficial plant compounds that may help prevent AMD and cataracts. No recommended daily intakes have been established, but a diet high in fruits and vegetables can provide plenty of these nutrients.
