Your macula, the pinhead-sized spot at the center of your retina, is covered by a thin layer of yellow pigment that absorbs blue light before it reaches the nerve cells underneath. Your body cannot make that pigment. After 50 it wears thin, the blur in the middle of your vision grows, and most eye vitamins never address it.
Athovita delivers lutein and zeaxanthin from marigold, carried in by the same four nutrients the National Eye Institute tested in its landmark AREDS trial: zinc, copper, vitamin C and vitamin E. That is the combination shown to move macular pigment, not lutein dropped into a capsule on its own.
