Keep Your Eyes Healthy With Zeaxanthin

Posted Oct 05 2010 2:15pm

Lucky Vitamin customers often search for products for eye health but many people are not familiar with the best ingredients for proper “eye nutrition”. Feeding your eyes is the most important thing you can do to ensure good vision.

Many foods contain a potent antioxidant called carotenoids. Several studies have shown that carotenoids may promote eye health through their ability to protect the eyes from light-induced oxidative damage and aging through both their antioxidant actions as well as their ability to filter out UV light. In addition, studies have noted that higher dietary intake of lutein and zeaxanthin is related to reduced risk of cataracts and age-related macular degeneration , two eye conditions with minimal options when it comes to effective prevention.
Whereas many people are familiar with lutein, most people do not know about zeaxanthin.

Zeaxanthin is the most potent antioxidan t carotenoid found in the retina and acts as a filter and shield against the damaging near-to-UV blue light from the sun.

Zeaxanthin is one of the two primary xanthophyll carotenoids contained within the retina of the eye. Within the central macula, zeaxanthin is the dominant component, whereas in the peripheral retina, lutein predominates. Zeaxanthin has been extensively tested and is considered “GRAF” (Generally Recognized As Safe) by the FDA.

Eggs, kale, spinach, goji berry, collard greens, romaine lettuce, broccoli, zucchini and corn are good sources of zeaxanthin.

Zeaxanthin works by supplying nutrients to the blood vessels in the eye. Once transported to the eye, zeaxanthin locates in several tissues, including the lens and in the macula region of the retina. The macula, located in the center of the retina, absorbs zeaxanthin, which it uses to filter high-energy light.
