Lutein is a xanthophyll and one of 600 known naturally occurring carotenoids. Lutein is synthesized only by plants and like other xanthophylls is found in high quantities in green leafy vegetables such as spinach and kale. In green plants, xanthophylls act to modulate light energy and serve as non-photochemical quenching agents to deal with triplet chlorophyll (an excited form of chlorophyll), which is overproduced at very high light levels, during photosynthesis.
Lutein is obtained by animals directly or indirectly, from plants. Lutein is apparently employed by animals as an antioxidant and for blue light absorption. Lutein is found in egg yolks and animal fats. In addition to coloring yolks, lutein causes the yellow color of chicken skin and fat, and is used in chicken feed for this purpose. The human retina accumulates lutein and zeaxanthin. The latter predominates at the macula lutea while lutein predominates elsewhere in the retina. There, it may serve to protect the retina from the ionizing effect of blue light.
Lutein is present in plants as fatty-acid esters, with one or two fatty acids bound to the two hydroxyl-groups. For this reason, saponification (de-esterfication) of lutein esters to yield free lutein may yield lutein in any ratio from 1:1 to 1:2 molar ratio with the saponifying fatty acid.
1. Promote healthy of eye and skin through reducing the risk of macular degeneration,
2. Be good at protecting the eyes, the arteries and the lungs from damaging free radicals,
3. Support normal eye function and protect the retina by blocking harmful blue light,
4. Reduce the risk of heart diseases and cancers.
Lutein was found to be concentrated in the macula, a small area of the retina responsible for central vision. The hypothesis for the natural concentration is that lutein helps keep the eyes safe from oxidative stress and the high-energy photons of blue light. Various research studies have shown that a direct relationship exists between lutein intake and pigmentation in the eye
Researchers from the University of Pennsylvania supplemented a group of patients suffering from choroideremia, a genetically-linked retinal disease that has no known cure, with 20 mg FloraGLO Lutein per day for 6 months . Results: This dose of lutein significantly increased both serum lutein levels and MPOD in these patients. This suggests that FloraGLO Lutein supplementation may benefit those with eye conditions other than AMD.
Dr.’s Aleman and Duncan of the University of Pennsylvania, supplemented a group of retinitis pigmentosa and usher syndrome patients with 20 mg FloraGLO Lutein per day for six months . Results: This dose of FloraGLO Lutein increased serum levels of lutein in all patients. Macular pigment optical density was significantly increased in half of the patients. This study was one of the first to show that macular pigment density may be improved in retinitis pigmentosa patients with FloraGLO Lutein supplementation.
