L-arginine Марка: NUTRIMКоличество: 120 таблетки L-аргинин на таблетки. L-аргининът е аминокиселина, използвана в организма за образуване на урея, при което се елеминира токсичният амоняк. L-аргининът е необходим за синтезата на креатин, вещество, участващо в преноса на фосфатни остатъци в процеса на ресинтеза на АТФ. При здрави хора, L-аргининът се образува в организма в достатъчно количество. В случаите на намалено хранене (малнутриция), на повишена продукция на амоняк, повишен прием на аминокиселината лизин, при изгаряния, инфекции, сепсис, перитонеална диализа и бърз растеж, синтезът на аргинин в организма може да се окаже недостатъчен. В ендотела на кръвоносните съдове аргининът е изходен субстрат за производство на азотен окис (NO). Чрез активиране на ензима гуанилатциклаза и последващото катализиране образуването на цГМФ, NO предизвиква разширение на съдовете. В тази връзка приложението на аминокиселината като хранителна добавка стимулира ендотелзависимата вазодилатация и подобрява кръвната циркулация в някои съдови области, вкл. и в скелетните мускули. L-аргининът участва в протеиновия синтез в организма. Подпомага заздравяването на раните, изграждането на мускули, производството на сперматозоиди, елиминирането на крайни токсични продукти на обмяната. Азотният окис, получен при добавянето към диетата на L-аргинин, освен разширяващ съдовете, има и антиатерогенен ефект. Потиска адхезията на мононуклеарните клетки, агрегацията на тромбоцитите и пролиферацията на гладкомускулни клетки в кръвоносните съдове. Антиоксидантният ефект на L-аргинина е свързан с потискане окислението на липопротеините с ниска плътност - едно от първите звена на веригата на атерогенеза. Притежава и имуномодулиращ ефект, проявяващ се чрез увеличаване количеството и цитотоксичната активност на естествените килърни клетки и лимфокин-активираните килърни клетки. Това го прави подходящ за ентерално приложение при случаи на изгаряния, сепсис и при травматични състояния. L-аргининът активира колагеновата биосинтеза. Състав L-аргинин микрокристална целулоза пълнител за таблетиране Ludipress магнезиев стеарат Дозировка и начин на употреба Три пъти дневно по 1-2 таблетки. Предлагани опаковки 120 таблетки по 1000 mg

It is classified as a semi-essential or conditionally essential amino acid. This means that under normal circumstances the body can synthesize sufficient L-arginine to meet physiological demands. There are, however, conditions where the body cannot. L-arginine is essential for young children and for those with certain rare genetic disorders in which synthesis of the amino acid is impaired. Some stress conditions that put an increased demand on the body for the synthesis of L-arginine include trauma (including surgical trauma), sepsis and burns. Under these conditions, L-arginine becomes essential, and it is then very important to ensure adequate dietary intake of the amino acid to meet the increased physiological demands created by these situations. L-arginine, even when it is not an essential amino acid as defined above, is a vital one. In addition to participating in protein synthesis, it plays a number of other roles in the body. These include the detoxification of ammonia formed during the nitrogen catabolism of amino acids via the formation of urea. In addition, L-arginine is a precursor in the formation of nitric oxide, creatine, polyamines, L-glutamate, L-proline, agmatin (a possible neurotransmitter in the brain) and the arginine-containing tetrapeptide tuftsin, believed to be an immunomodulator. L-arginine is a glycogenic amino acid; it can be converted to D-glucose and glycogen if needed by the body or it can be catabolized to produce biological energy. L-arginine, when administered in high doses, stimulates pituitary release of growth hormone and prolactin and pancreatic release of glucagon and insulin. Intravenous L-arginine may be used as an aid in the evaluation of problems with growth and stature that may be due to growth hormone deficiency. Intravenous arginine hydrochloride may be used as a fourth-line agent in the treatment of severe metabolic alkalosis. L-arginine is also used as an immunonutrient in enteral and parenteral nutrition to help improve the immune status in those suffering from sepsis, burns and trauma. L-arginine is predominately synthesized in the kidney. It is a key intermediate in the Krebs-Henseleit urea cycle. L-ornithine and L-citrulline are precursors in the synthesis of L-arginine, and L-arginine is converted to urea and L-ornithine via the enzyme arginase. The portion of L-arginine that is not converted to urea enters the circulation, and is distributed to the various tissues and metabolized as discussed above. A much smaller amount of L-arginine is produced in the liver. Most dietary L-arginine comes from plant and animal proteins. Small amounts of free L-arginine are found in vegetable juices and fermented foods, such as miso and yogurt. Soy protein and other plant proteins are richer in L-arginine than are animal proteins, which are richer in lysine. It is thought that the possible hypocholesterolemic effect of soy protein is due, at least in part, to the higher L-arginine content in this protein. CONTRAINDICATIONS Supplemental L-arginine is contraindicated in those with the rare genetic disorder argininemia. It is also contraindicated in those hypersensitive to any component of an arginine-containing preparation. PRECAUTIONS Because of absence of long-term safety studies, and because of the possibility of growth hormone stimulation, pregnant women and nursing mothers should avoid L-arginine supplementation. Those with renal or hepatic failure should exercise caution in the use of supplemental L-arginine. Proteins of the herpes simplex virus are rich in L-arginine, and there are a few reports (mainly anecdotal) of those taking supplemental L-arginine who have had recurrences of oral herpes lesions. Although it is unlikely that those with a history of herpes simplex virus infection will have recurrences if they use L-arginine supplements, they should nevertheless be aware of this possibility. ADVERSE REACTIONS Oral supplementation with L-arginine at doses up to 15 grams daily are generally well tolerated. The most common adverse reactions of higher doses — from 15 to 30 grams daily — are nausea, abdominal cramps and diarrhea. Some may experience these symptoms at lower doses. INTERACTIONS DRUGS Cyclosporine: L-arginine may counteract the antinaturetic effect of cyclosporin. Ibuprofen: L-arginine may increase the absorption of ibuprofen if taken concomitantly. Organic nitrates: L-arginine supplements theoretically may potentiate the effects of organic nitrates if taken concomitantly. Sildenafil citrate: Theoretically, L-arginine supplements taken concomitantly with sildenafil citrate, may potentiate the effects of the drug. HERBS Yohimbe: L-Arginine, if used concomitantly, may enhance the effect of yohimbe. Directions: Shake well. Add 5 level scoop to 6-8 oz. water once daily as a dietary supplement, or as directed by a health care professional., , Antioxidants, Antioxidants, , purenaturalhealth.co.uk, Antioxidants, , Healthy Flow™ (replaces Nitrix and Argenix) Powder developed by developed by SEO Stoke-on-Trent Cybernautix - White Box Ecommerce Solutions
