Product Details

Lutein and zeaxanthin have identical chemical formulas and are isomers, but they are not stereoisomers. The main difference between them is in the location of a double bond in one of the end rings. This difference gives luteinthree chiral centers whereas zeaxanthin has two. A relationship between macular pigment optical density, a marker of lutein and zeaxanthin concentration in the macula, and lens optical density, an antecedent of cataractous changes, has been suggested. The xanthophylls may act to protect the eye from ultraviolet phototoxicity via quenching reactive oxygen species and/or other mechanisms. Some observational studies have shown that generous intakes of lutein and zeaxanthin, particularly from certain xanthophyll-rich foods like spinach, broccoli and eggs, are associated with a significant reduction in the risk for cataract (up to 20%) and for age-related macular degeneration (up to 40%). While the pathophysiology of cataract and age-related macular degeneration is complex and contains both environmental and genetic components, research studies suggest dietary factors including antioxidant vitamins and xanthophylls may contribute to a reduction in the risk of these degenerative eye diseases.

Main Function of Lutein :

1.An eye disease called age-related macular degeneration (AMD). Population studies suggest that people who consume higher amounts of lutein in their diet have a reduced risk of developing AMD. However, increasing dietary intake of lutein might not reduce the risk of AMD in people who already have a high intake of lutein. Taking lutein supplements for up to 12 months can improve some symptoms of AMD, but it does not seem to prevent AMD from becoming worse. Research on the use of lutein together with other ingredients shows conflicting results.

2.Cataracts. Some studies suggest that eating higher amounts of lutein might decrease the risk of developing cataracts. Also, early research suggests that taking lutein three times weekly for up to 2 years can improve vision in elderly people with cataracts.
