Lutein- one of the most common Carotenoids widely presented in plants especially dark-green leafy vegetables. Lutein is synthesized only by plant itself and like other xanthophylls which is usually found in green leafy vegetables such as spinach, kale and Marigold Flower.

In green plants, lutein act as modulate light energy and serve as a non-photochemical quenching agents to deal with triplet chlorophyll (an excited form of chlorophyll), which is over produced at very high light levels, during photosynthesis. Lutein is also a very important natural yellow pigment in our lives due to its color.

1.A major component of retinal pigment: lutein and zeaxanthin constitutes a major component of vegetables, fruits, flowers and other plant pigments, as well as the human eye macular area main pigment. The human eye contains high levels of lutein, this element can not be manufactured by the body and must be supplemented by the intake of lutein, if the lack of such elements, the eyes will be blind;  

2.Protect the eyes from light damage, slow aging and prevent diseases of the eye: the sun's ultraviolet radiation and blue light entering the eye will produce a lot of free radicals, leading to cataracts, macular degeneration, and even cancer. General cornea and lens UV filter can, but they can penetrate the eye directly to Blu-ray and macular retina, macular lutein is able to filter out blue light, blue light to avoid damage to the eyes. Fat outer macular are particularly vulnerable to oxidative damage of sunlight, so this area prone to degradation;

3.Antioxidant, helps prevent aging body caused by cardiovascular sclerosis, coronary heart disease and cancer.  

4.Protect vision: Lutein as antioxidants and light protection, promotes retinal cells rhodopsin (Rhodopsin) re-generated, can prevent severe myopia and retinal detachment, and can improve vision, protect eyesight. Especially for students, drivers, and human consumption;  

5.Relieve visual fatigue symptoms: (blurred vision, dry eyes, eye swelling, eye pain, photophobia, etc.

6.Raise macular pigment density, protecting the macula, macular promote development;  

7.Prevent macular degeneration and retinitis pigmentosa;  

8.To reduce the generation of drusen, prevent the occurrence of AMD.

Lutein can lower the risk of age related vision loss, which causes gradual loss of central vision. Age related vision loss or age related macular degeneration (AMD) is caused by steady damage of the retina.

Lutein probably acts by preventing oxidative damage of the retina cells.

Lutein is concentrated in the central part of the retina, called the macula. In the macula are yellow pigments (macular pigments composed of zeaxanthin and lutein) which protect the retina from damage of the photo-oxidative affect of blue light.

Lutein can also reduce the risk for artery diseases. Studies have shown that persons with the highest lutein intake showed the lowest artery wall thickening.

Lutein also reduces the oxidation of LDL cholesterol thereby reducing the risk of artery clogging.

Lutein can also reduce the risk of skin cancer and sunburn. Under influence of sunlight, free radicals are formed inside the skin.
