Lutein is an 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, kale and yellow carrots. 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 was found to be present in a concentrated area of the macula, a small area of the retina responsible for central vision. The hypothesis for the natural concentration is that lutein helps protect from oxidative stress and high-energy light. Several studies show that an increase in macula pigmentation decreases the risk for eye diseases such as Age-related Macular Degeneration (AMD).
Selenium is a trace metal in the human body particularly important as a component of glutathione peroxidase, an important enzyme in the prevention of cellular damage by free radicals and reactive oxygen species
Selenium is incorporated into many different selenoproteins which serve various functions throughout the body .
Vitamin E Capsule is a Vitamin E preparation. Vitamin E acts as an antioxidant in the body. Vitamin E protects polyunsaturated fatty acids (which are components of cellular membrane) and other oxygen-sensitive substances such as vitamin A & vitamin C from oxidation. Vitamin E reacts with free radicals, which is the cause of oxidative damage to cell membranes, without the formation of another free radical in the process. The main pharmacological action of vitamin E in humans is its antioxidant effect.
In premature neonates irritability, edema, thrombosis and hemolytic anemia may be caused due to vitamin E deficiency. Creatinuria, ceroid deposition, muscle weakness, decreased erythrocyte survival or increased in vitro hemolysis by oxidizing agents have been identified in adults and children with low serum tocopherol concentrations.
Vitamin E is a collective term used to describe 8 separate fat soluble antioxidants, most commonly alpha-tocopherol. Vitamin E acts to protect cells against the effects of free radicals, which are potentially damaging by-products of the body's metabolism. Vitamin E deficiency is seen in persons with abetalipoproteinemia, premature, very low birth weight infants (birth weights less than 1500 grams, or 3½ pounds), cystic fibrosis, and cholestasis and severe liver disease. Preliminary research suggests vitamin E may help prevent or delay coronary heart disease and protect against the damaging effects of free radicals, which may contribute to the development of chronic diseases such as cancer. It also protects other fat-soluble vitamins (A and B group vitamins) from destruction by oxygen. Low levels of vitamin E have been linked to increased incidence of breast and colon cancer.
Zeaxanthin is a most common carotenoid alcohols found in nature that is involved in the xanthophyll cycle. As a coexistent isomer of lutein, zeaxanthin is synthesized in plants and some micro-organisms. It gives the distinct yellow color to many vegetables and other plants including paprika, corn, saffron and wolfberries. Zeaxanthin is one of the two primary xanthophyll carotenoids contained within the retina of the eye and plays a predominant component in the central macula. It is available as a dietary supplement for eye health benefits and potential prevention of age-related macular degeneration. Zeaxanthin is also added as a food dye.

How Lubire works
Xanthophylls have antioxidant activity and react with active oxygen species, producing biologically active degradation products. They also can inhibit peroxidation of membrane phospholipids and reduce lipofuscin formation, both of which contribute to their antioxidant properties. Lutein is naturally present in the macula of the human retina. It filters out potentially phototoxic blue light and near-ultraviolet radiation from the macula. The protective effect is due in part, to the reactive oxygen species quenching ability of these carotenoids. Lutein is more stable to decomposition by pro-oxidants than are other carotenoids such as beta-carotene and lycopene. Lutein is abundant in the region surrounding the fovea, and lutein is the predominant pigment at the outermost periphery of the macula. Zeaxanthin, which is fully conjugated (lutein is not), may offer somewhat better protection than lutein against phototoxic damage caused by blue and near-ultraviolet light radiation. Lutein is one of only two carotenoids that have been identified in the human lens, may be protective against age-related increases in lens density and cataract formation. Again, the possible protection afforded by lutein may be accounted for, in part, by its reactive oxygen species scavenging abilities. Carotenoids also provide protection from cancer. One of the mechanisms of this is by increasing the expression of the protein connexin-43, thereby stimulating gap junctional communication and preventing unrestrained cell proliferation.
Selenium is first metabolized to selenophosphate and selenocysteine. Selenium incorporation is genetically encoded through the RNA sequence UGA . This sequence is recognized by RNA ste loop structures called selenocysteine inserting sequences (SECIS). These structures require the binding of SECIS binding proteins (SBP-2) to recognize selenocystiene. The specialized tRNA is first bound to a serine residue which is then enzymatically processed to a selylcysteyl-tRNA by selenocystiene sythase using selenophosphate as a selenium donor. Other unidentified proteins are required as part of the binding of this tRNA to the ribosome. Selenoproteins appear to be necessary for life as mice with the specialized tRNA gene knocked out exhibited early embryonic lethality .
The most important selenoproteins seem to be the glutathione peroxidases and thioredoxin reductases which are part of the body's defenses againts reactive oxygen species (ROS) . The importance of selenium in these anti-oxidant proteins has been implicated in the reduction of atherosclerosis by preventing the oxidation of low density lipoprotein . Selenium supplementation is also being investigated in the prevention of cancer and has been suggested to be beneficial to immune function .
The mechanism of action for most of vitamin E's effects are still unknown. Vitamin E is an antioxidant, preventing free radical reactions with cell membranes. Though in some cases vitamin E has been shown to have pro-oxidant activity.
One mechanism of vitamin E's antioxidant effect is in the termination of lipid peroxidation. Vitamin E reacts with unstable lipid radicals, producing stable lipids and a relatively stable vitamin E radical. The vitamin E radical is then reduced back to stable vitamin E by reaction with ascorbate or glutathione.

Side Effects
Overdoses (>1g) have been associated with minor side effects, including hypertension, fatigue, diarrhea and myopathy
Toxicity
Oral LD50 of 6700mg/kg in rats . Selenium exposure is teratogenic and can result in fetal death as tested in mice. Chronic toxicity is characterized by hair loss, white horizontal streaking on fingernails, paronchyia, fatigue, irritability, hyperreflexia, nausea, vomiting, garlic odor on breath, and metallic taste . Serum selenium correlates weakly with symtoms. Blood chemistry as well as liver and kidney function are normally unnaffected. Acute toxicity presents as stupor, respiratory depression, and hypotension. ST elevations and t-wave changes characteristic of myocardial infarction may be observed.
There is no data available for effects in pregnancy, breast feeding, hepatic impairment, or renal impairment. However, it appears that the process of vitamin E elimination is strict and self regulating enough that vitamin E toxicity is exceedingly rare. Studies showing adverse effects from excess vitamin E generally involve people consuming more than 1000mg/day for weeks to months.
Precaution
Vitamin E may enhance the anticoagulant activity of anticoagulant drugs. Caution is advised in premature infants with high dose Vitamin E supplementation, because of reported risk of necrotizing enterocilitis.
Interaction
Vitamin E may impair the absorption of Vitamin A. Vitamin K functions impairement happens at the level of prothrombin formation and potentiates the effect of Warfarin.
Volume of Distribution
0.41L/kg in premature neonates given a 20mg/kg intramuscular injection.
Elimination Route
Oral bioavailability of 90% when given as L-selenomethionine . Tmax of 9.17h.
10-33% of deuterium labelled vitamin E is absorbed in the small intestine. Absorption of Vitamin E is dependant upon absorption of the fat in which it is dissolved. For patients with poor fat absorption, a water soluble form of vitamin E may need to be substituted such as tocopheryl polyethylene glycol-1000 succinate.
In other studies the oral bioavailability of alpha-tocopherol was 36%, gamma-tocotrienol was 9%. The time to maximum concentration was 9.7 hours for alpha-tocopherol and 2.4 hours for gamma-tocotrienol.
Half Life
Half life was observed to increase with chronic dosing time . For day 1-2 half life was 1.7 days. For day 2-3 half life was 3 days. For day 3-14 half life was 11.1 days.
44 hours in premature neonates given a 20mg/kg intramuscular injection. 12 minutes in intravenous injection of intestinal lymph.
Clearance
6.5mL/hr/kg in premature neonates given a 20mg/kg intramuscular injection.
Elimination Route
Mainly excreted in urine as 1beta-methylseleno-N-acetyl-d-galactosamine and trimethylselenonium . The amount excreted as 1beta-methylseleno-N-acetyl-d-galactosamine plateaus at doses around 2microg after which the amount excreted as trimethylselenonium increases. Some selenium is also excreted in feces when given orally .
Alpha tocopherol is excreted in urine as well as bile in the feces mainly as a carboxyethyl-hydrochroman (CEHC) metabolite, but it can be excreted in it's natural form .
