Zeaxanthin supplement

Zeaxanthin is one of the most common carotenoid alcohols found in nature. Xanthophylls such as zeaxhanthin are found in highest quantity in the leaves of most green plants. Animals derive zeaxanthin from a plant diet. 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.
Lutein and zeaxanthin have identical chemical formulas and are isomers, but they are not stereoisomers. According to a 1995 study, increasing the consumption of dark green, leafy vegetables appears to offer some protection against macular degeneration. These are obtained primarily from dark green, leafy vegetables such as spinach, collard greens, kale, mustard greens, and turnip greens.
On April 7, 2004 the North Chicago VA Medical Center issued a press release announcing that lutein has been shown to not only help prevent, but to actually reverse symptoms of ARMD. Patients ingesting the lutein supplement experienced significant improvements in several objective measurements of visual function including glare recovery, contrast sensitivity, and visual acuity vs. placebo.
Lutein and zeaxanthin as food additives are two of the most abundant carotenoids in the North American diet. In recent years, carotenoids have received a tremendous amount of attention as potential anti-cancer and anti-aging compounds. Researchers speculate that these 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.
