What is lutein?
Lutein is also known as "plant progesterone", existing together with zeaxanthin in nature. It is the main component of the plant pigments such as corns, vegetables, fruits, flowers and so on, contained in the chloroplasts of leaves, can pass the light energy absorbed to lutein A, with the protective effect on light oxidation and photo-damage. It is also the main pigment to form the retina macular region of the human eyes.
Lutein is a natural substance widely found in vegetables, flowers, fruits and other plants, belonging to the "family of carotenoid". There are 600 carotenoids substances which were discovered so far, existing in the natural world, but only about 20 were found in human blood and tissue. The carotenoids found in the human body were mainly consisted of Alpha-carotene, beta-carotene, genistein, lutein and lycopene.
Lutein is the main retinal primary pigment and also is a powerful antioxidant, capable of absorbing the screen blue-ray to protect the retinal health. With the increasingly frequent use of electronic products, there are many eye diseases such high myopia, retinopathy and others, which has a great impact on the quality of life for individuals and families, so it becomes more and more important to protect eye health.
- As a pigment: Orange natural pigment is widely used in chicken feed and also in some food, but the scope is limited because they do not dissolve in water.
- Eye protection: Lutein can absorb blue light. The sun's ultraviolet, blue light into eyes will produce a large number of free radicals, cause cataracts, macular degeneration and even cancer. The human's eye contains high level of lutein which can not be produced by human' bodies and which must be supplemented by intake of it. Studies show that intake of lutein will help slow the aging, degradation, disease occur of eyes and reduce the incidence of eye-diseases and protect the retina from light damage.
- Antioxidant: The latest studies show that lutein is helpful for the treatment of heart disease and may prevent arterial wall thickening.
How lutein works:
Lutein is one of two major carotenoids found as a color pigment in the human eye (macula and retina). It is thought to function as a light filter, protecting the eye tissues from sunlight damage.
Most studies examining the effects of lutein have looked at its effects on eye health. The University of Michigan Health System points to one trial that found that supplementing with 15 mg of lutein three times a week for one year significantly improved visual function in subjects suffering from cataracts. The University of Pittsburgh Medical Center reports that one trial study found that taking 10 mg a day resulted in improved vision in patients with macular degeneration, but another trial using only 6 mg failed to show any benefit.
Don’t take it without consulting your doctor or when you don’t know the appropriate dosage.
