Amino acids are organic compounds that combine to form proteins - the basic building blocks of proteins . These proteins are crucial for the growth , repair and maintenance of cells and tissues .

There are twenty basic amino acids, nine of which are essential , meaning we must obtain them through the diet because the body cannot synthesize them. Essential amino acids such as arginine , leucine , isoleucine , lysine , methionine , phenylalanine , threonine , tryptophan , and valine are essential for muscle repair, enzyme production, and neurotransmitter function.

These substances are important for supporting health, hormones, enzymes, antibodies, neurotransmitters, muscles, joints, bones and much more.

At Nutraday, you'll find a wide variety of amino acids in different forms and dosages to suit your individual needs, including essential , non-essential and conditionally essential amino acids.

Co jsou esenciální aminokyseliny?

Esenciální aminokyseliny zahrnují histidin, izoleucin, leucin, lysin, methionin, fenylalanin, threonin, tryptofan a valin, které tělo nemůže syntetizovat a musí být přijaty prostřednictvím potravy nebo doplňků.

Které potraviny jsou bohaté na aminokyseliny?

Živočišné proteiny jako kuře, hovězí, a losos jsou bohaté na esenciální aminokyseliny. Pro vegetariány a vegany, kombinace různých rostlinných potravin jako fazole a rýže může poskytnout všechny nezbytné aminokyseliny.

Arginine and citrulline are two amino acids that are integral to protein metabolism and utilization, as well as the maintenance of muscle tissue. Both are key intermediates in the urea cycle where they participate in ammonia detoxification through the production of urea. In addition, arginine that is not used to make urea enters the general circulation, where it is then distributed to various tissues and metabolized for other uses, such as protein synthesis. The product also contains citrulline, which is itself a more effective source of arginine, but lacks some of the properties of arginine. Together, these two amino acids form an ideal combination for increasing NO, pumping muscles, and improving blood flow.

L-Prolin je aminokyselina, která je spolu s aminokyselinou L-Cystein nezbytná pro produkci kolagenu. Kolagen je hlavní strukturální protein, který tvoří všechny lidské pojivové tkáně, včetně kůže, šlach, vazů, kloubů, kostí a krevních cév (žil a tepen). L-Prolin je proto stavebním kamenem, který pomáhá stabilizovat a posílit strukturální složky těla. Ačkoli je Prolin přirozeně syntetizován v těle, v situacích s vysokou poptávkou a při absenci správných potravin nemusí být běžná strava dostatečná k tomu, aby pokryla veškerou potřebu prolinu v těle a produkci kolagenu.

Aminokyselina L-glutamin je neesenciální aminokyselina produkovaná tělem, která slouží jako stavební blok pro proteiny. Pomáhá také dodávat palivo do imunitních buněk uvnitř trávicího traktu. L-Glutamin je nejhojnější aminokyselinou v krvi a svalové tkáni. Během stresu nebo náročného cvičení však může být přirozená hladina L-glutaminu snížena. Z tohoto důvodu mnoho sportovců přidává l-glutamin do své stravy a cvičebního programu. Velmi důležitým důvodem však schopnost glutaminu snižovat přirozené odbourávání svalů, což se velmi hodí při budování svalů a jejich regeneraci. L-Glutamin může pomoci optimalizovat sportovní výkon, podpořit udržení svalů a zdravou funkci buněk v GI traktu. Ačkoliv tělo přirozeně dle potřeby snadno přeměňuje kyseliny jako glutamin, histidin, ornithin a další na glutamát, nejedná se o to samé jako požití většího množství čistého glutamátu sodného, například při konzumaci rychlého občerstvení, případně tzv. “syndrom asijské kuchyně” apod, který může způsobit zdravotní obtíže. Přesto osoby, které jsou citlivé na glutamát sodný mohou být citlivé i na větší množství aminokyseliny L-Glutamin.
