With aging, our eyes and the associated muscles weaken. They can degenerate and lose our ability to see properly. Eyes enable us with vision to see the world, and losing the eyesight will halt affect our daily activities and movements. People are frequently worried about losing their sight, and try to find supplements that can prevent the loss of vision. However, this debility can be prevented.
Supplements should be ideally be all natural, healthy, and with no side effects. Zeaxanthin is an important nutrient for eye health. This is found in found in green leafy vegetables, and also in other foods like eggs. Zeaxanthin fulfills most of the requirements that most people look in a supplement.
WHAT IS ZEAXANTHIN
Zeaxanthin and lutein are carotenoids that filter out the harmful high-energy wavelengths of light, and also act as antioxidants in the eye. This helps to maintain and protect healthy eye cells. Out of the six hundred carotenoids found in nature, only these two, Zeaxanthin and Lutein are deposited in high quantities in the retina (macula) of the eye. Unfortunately, our body does not synthesize the zeaxanthin and lutein it requires.
This is the reason why green vegetables, eggs and other sources of these carotenoids are essential to proper nutrition. Daily intake of zeaxanthin and lutein through diet, beverages, fortified foods or nutritional supplements and is very important for the protection and continuation of good eye health.
Studies have indicated that zeaxanthin and lutein can help to lessen the chance of chronic eye illnesses, including cataracts and age-related macular degeneration (AMD).
Zeaxanthin, is also a bioflavonoid, that besides its benefits to ocular health, has been linked to providing many health benefits, including its anti-inflammatory property. Because of zeaxanthin being a carotenoid category bioflavonoid, its main action is over the blood vessels; it works by supporting the blood vessels around the retina area with their proper function.
Zeaxanthin is both an anti-inflammatory phytochemical and an antioxidant; hence this has been used as a preventative measure for macular degeneration and cataracts. Its antioxidant properties keep eyes from being damaged from the harmful ultraviolet rays of the sunlight. Overall, zeaxanthin keeps the eye healthier, and looking younger.
ZEAXANTHIN AGAINST CATARACT: Our natural eye collects and focuses light on the retina, and to properly provide this function continuously, the lens must remain clear throughout life. A major cause of cataracts is oxidation of the lens, which clouds it. Antioxidant nutrients, like zeaxanthin and lutein neutralize the free radicals or the unstable molecules associated with this oxidative stress associated with retinal damage. Thus, these phytochemicals play a role in cataract prevention. Higher dietary intakes of vitamin E, zeaxanthin and lutein can considerably reduce the risk of cataract formation.
ZEAXANTHIN AGAINST AGE-RELATED MACULAR DEGENERATION (AMD): Zeaxanthin and lutein reduces the risk of AMD. In fact, studies like AREDS2 (Age-Related Eye Disease Study) are being conducted with supplements containing ten mg lutein along with two mg zeaxanthin each day, how it affects or lowers the chance of developing this degeneration.
FOOD SOURCES OF ZEAXANTHIN
Zeaxanthin is naturally found in some green leafy vegetables like kale and spinach. Other sources of zeaxanthin include egg yolk, yellow squash and bell-peppers. This makes zeaxanthin available as a completely natural nutrient, with no side effects.
