L-norvaline is another amino acid that finds application in sports supplementation. Despite the relatively limited amount of information about it and the continuous treatment as a "unique compound", this substance is increasingly being used as an ingredient in many dietary supplements. Discover then, what benefits the use of this preparation brings during work on your own physique.

What is l-norvaline and what is its purpose?

L-norvaline is a chemical compound that belongs to the group of branched and non-protein amino acids. This means that the compound is not present in protein molecules and does not form an amino acid protein profile. L-norvaline is also one of the most popular isomers of the amino acid valine, which is part of the BCAA complex together with leucine and isoleucine. L-norvaline is a relatively new amino acid that has only recently begun to be used in sports supplementation.

Function and use of L-Norvaline

Despite its young age, L-Norvaline is a substance that is enthusiastically accepted not only by bodybuilders but also by the entire sports world. L-Norvaline contributes to delaying the breakdown of compounds known as guanidines, four of which have an effect on the body. The greatest effect of norvaline is observed in the context of arginine. Arginine is one of the main representatives of nitrogen boosters, which means that it is a component of most creatine stacks and pre-workout supplements. Norvaline contributes to the deactivation of arginase - a hormone that leads to the breakdown of L-arginine into urea and ornithine. It is assumed that in typical conditions (without L-norvaline supplementation), arginine losses can reach up to 75%! The consequence of an additional dose of L-norvaline is the use of a larger amount of arginine for the production of nitric oxide, which in turn leads to a stronger muscle pump effect and better muscle nourishment. The inhibition of arginase activity enhances the anabolic character of arginine. This leads to an increased synthesis of growth hormones, improved post-workout regeneration, more effective detoxification of the body, and delayed aging process. Other valuable guanidines include the very popular creatine and guanidinopropionate. Both compounds are substances that are converted into creatine in our body. It can therefore be safely stated that L-norvaline enhances the effect of creatine supplements and directly contributes to increased energy production in our body. The last and particularly important property of L-norvaline is the prevention of the removal of ammonium ions. These particles are very helpful in the process of deacidifying our body. In addition to the typical reduction of acidic pH in the cellular environment, ammonium ions are a reservoir of extracellular nitrogen molecules, which enhance anabolic processes in muscle-building proteins.

Dosage and occurrence of norvaline

Norvaline is rarely found as a standalone supplement or in pure form. It is most commonly found in dietary supplements, especially in pre-workout formulas and creatine stacks. L-norvaline usually accompanies substances such as arginine or creatine. Additionally, it often appears in combination with beta-alanine or citrulline, which are also popular additions to this type of supplement. The dosage of norvaline can be determined based on other ingredients that are present in the product in which it is contained. Typically, the dose ranges from 50 to 200 mg.
