Beta-carotene, with the molecular formula C40H56, belongs to the group of carotenoids consisting of isoprene units. The presence of long chains of conjugated double bonds donates beta-carotene with specific colors. It is the most abundant form of carotenoid and it is a precursor of the vitamin A. Beta-carotene is composed of two retinyl groups. It is an antioxidant that can be found in yellow, orange and green leafy vegetables and fruits. Under the FDA, beta-carotene is considered as a generally recognized as safe substance (GRAS).
Oral administration of beta-carotene increases the serum concentration of beta-carotene by 60% but it does not change the concentration found in the heart, liver or kidneys. In vitro studies in hepatocytes have shown that beta-carotene ameliorates oxidative stress, enhances antioxidant activity and decreases apoptosis.
Other than the antioxidant activities, some other actions have been correlated to beta-carotene. It is thought to have detoxifying properties, as well as to help increase resistance to inflammation and infection and increase immune response and enhance RNA production.
Active fraction of Solanum trilobatum; reduces side-effects of radiation-induced toxicity.
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 .

Uses
Beta carotene is a vitamin A precursor found in various nutritional supplements and health products.
Beta-carotene is FDA approved to be used as a nutrient supplement and to be even added in infant formula as a source of vitamin A. It is also approved to be used as a color additive for food products, drugs (with the label of "only as a color additive") and cosmetics.
It is used commonly for the reduction of photosensitivity in patients with erythropoietic protoporphyria and other photosensitivity diseases.
Selenium is an ingredient found in a variety of supplements and vitamins.
For the supplementation of total parenteral nutrition to prevent hyposelenemia .
Nutrimax Prost Care is also used to associated treatment for these conditions: Deficiency, Vitamin A, Nutritional supplementationBurns, Periodontal Diseases, WoundsNutritional supplementation
How Nutrimax Prost Care works
Beta-carotene is an antioxidant that presents significant efficacy against the reactive oxygen species singlet oxygen. Beta-carotene acts as a scavenger of lipophilic radicals within the membranes of every cell compartments. It also presents an oxidative modification of LDL. The presence of long chains of conjugated double bonds is responsible for its antioxidative properties by allowing beta-carotene to chelate oxygen-free radicals and dissipate their energy. The chelation of free radicals inhibits the peroxidation of lipids.
The effect of beta-carotene in the immune response is thought to be related to the direct effect on the thymus which increases the production of immune cells.
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 .
Toxicity
Beta-carotene is not toxic but the high and constant administration of this substance can translate into skin yellow coloration. Some reports have indicated that administration of high and periodic doses of beta-carotene are correlated to the increase in cancer incidence. This risk seems to be very elevated in the case of smokers. The registered LD50 of beta-carotene is >5000 mg/kg.
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.
Volume of Distribution
No pharmacokinetic studies have been performed regarding the volume of distribution of beta-carotene.
Elimination Route
After administration of beta-carotene, some of the administered dose is absorbed into the circulatory system unchanged and stored in the fat tissue. The coadministration of beta-carotene and a high-fat content diet is correlated to a better absorption of beta-carotene. The absorption is also dependent on the isomeric form of the molecule where the cis conformation seems to present a higher bioavailability. The absorption of beta-carotene is thought to be performed in 6-7 hours.
The reported AUC of beta-carotene when administered orally from 0 to 440 hours after initial administration was reported to be 26.3 mcg.h/L. The maximal concentration of beta-carotene is attained in a dual pharmacokinetic profile after 6 hours and again after 32 hours with a concentration of 0.58 micromol/L.
Oral bioavailability of 90% when given as L-selenomethionine . Tmax of 9.17h.
Half Life
The apparent half-life of beta-carotene is of 6-11 days after initial administration.
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.
Clearance
The clearance rate of beta-carotene administered orally is 0.68 nmol/L each hour.
Elimination Route
The unabsorbed carotene is excreted in feces. It is also excreted in feces and urine as metabolites. The consumption of dietary fiber can increase the fecal excretion of fats and other fat-soluble compounds such as beta-carotene.
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 .
