Zeaxanthin is a powerful, natural antioxidant that protects the eye by absorbing damaging blue light and reducing glare. Blue light can cause harmful oxidative stress in the eye. Zeaxanthin protects cells and membranes by reducing harmful free radicals. It is one of the two most important carotenoids in the retina - while lutein is found mostly in the edge of the retina, zeaxanthin is predominant in the central macula.

Zeaxanthin is a nutrient found in nature as colorants or pigment. It is also found in vegetables such as kale, plus various fruits and corn. Marigolds are also sources of zeaxanthin. Zeaxanthin is found naturally in the body, predominantly in the eyes and brain. Thus it is extremely important in fighting macular conditions such as macular degeneration and maintaining healthy vision.
