General instructions
Lutein is a naturally occurring antioxidant. It protects and improves eye function. It is part of a group of substances called carotenoids. Lutein and other carotenoids, such as zeaxanthin, may help prevent or slow down macular degeneration. This is a disease of the eye. It is one of the leading causes of blindness in people over the age of 60.
Lutein is first isolated from egg yolks. It is one of the pigments in the petals of yellow flowers and the feathers of birds.
Lutein and zeaxanthin are the most common carotenoids found in nature. They can find leafy greens like broccoli, peas, lettuce, parsley, spinach and kale. They are also found in egg yolks.
medically valid uses
The use of lutein or zeaxanthin supplements has not been proven. But lutein, zeaxanthin, and other carotenoids such as beta-carotene can prevent or slow down macular degeneration. Of all the pigments in the macula, lutein has the highest content. The macula is the part of the retina that produces sharp vision.
The role of lutein and zeaxanthin is to protect the retina of the eye from aging. They also protect it from UV rays. They act as antioxidants to the retina. They protect fragile retinal blood vessels from oxidative damage. This damage may lead to hardening changes in the lining of the blood vessels. Over time, this can lead to macular degeneration. As pigments, they block harmful types of light from being absorbed by the sensitive retina.
These carotenoids may prevent macular degeneration. But they may not treat the condition once you have it. In the years before you start to develop macular degeneration, you need to eat a diet that contains enough lutein. This will bring the greatest benefit.
Clinical studies have also shown that lutein’s antioxidant and anti-inflammatory properties may protect and alleviate other eye diseases such as cataracts, diabetic retinopathy, myopia, and retinopathy of prematurity.
unsubstantiated claims
There may be benefits that haven't been proven by research.
Lutein may help reduce hardening of the arteries (atherosclerosis). The risk of cataracts may also be reduced.
