Zeaxanthin is a carotenoid found in the retina of the eye and can be obtained through a balanced diet or supplements. Studies suggest it may protect against age-related eye conditions. Rich food sources include paprika, corn, and saffron. It protects the eye from photo damage and oxidation and may improve vascular health. Regular eye exams are important for early detection of eye problems.
Zeaxanthin is a carotenoid compound found in the retina of the eye. In the macula, an area in the center of the retina, high concentrations of zeaxanthin are present, with lower concentrations of lutein, a related compound. In the rest of the retina, lutein predominates, with lower levels of zeaxanthin. There are numerous food sources for this compound, and most people who eat a balanced diet get all the zeaxanthin they need to stay healthy. It is also possible to take supplements.
Studies done on the eye seem to suggest that zeaxanthin may play an important role in eye health. People who consume six to 10 milligrams a day of this compound are less likely to develop age-related macular degeneration and appear to be less likely to suffer from cataracts. Because these conditions are commonly associated with aging, many people are interested in knowing how to prevent them, and studies on zeaxanthin and lutein have therefore attracted a lot of attention.
Paprika, corn, saffron and a variety of other vegetables are rich in this compound, which is also used as a food coloring in some regions of the world. Eating vitamin C with zeaxanthin appears to increase the body’s ability to absorb it. People who feel they are not getting enough of this compound through their diet can take standalone supplements or combination supplements that include it. Consumers may want to know that it is usually safe to take more than the recommended daily amount.
This compound works in the eye in several ways. It appears to protect the eye from photo damage by filtering out certain types of light, and it also protects against oxidation, a common cause of damage associated with aging. Zeaxanthin may also be involved in vascular health of the eye; without good circulation, the eye can be vulnerable to infection and other types of damage.
People interested in protecting eye health with products such as zeaxanthin and lutein supplements should also ensure they are under the care of an ophthalmologist. Regular eye exams are an important part of eye care, as they can be used to identify eye problems in their early stages, at which point it’s easier to intervene to prevent continued damage. Regular eye exams can also be important as they can detect symptoms of an underlying disease that otherwise would not be addressed until it is too late.
