Arginine in the composition of pre-workout complexes

Arginine is often included in the composition of pre-workout complexes, as it has transport properties. For maximum results, it is recommended to use supplements of this class on training days, and on rest days – pure arginine + creatine.

Arginine (or L-Arginine) is a conditionally essential aliphatic amino acid, often produced in the form of a mono-hydrochloride salt (L-Arginine HCL). It is used in sports nutrition as a nitrogen donor.

In the body, arginine is exposed to a system of enzymes called NO synthases, which synthesize NO, or nitric oxide, from it. Nitric oxide is a mediator that regulates the tone of blood vessels of the arterial bed, on which blood pressure and nutrition of all organs and tissues, including muscles, depend. With a lack of arginine and insufficient activity of NO-synthases, blood pressure increases.

Structure of arginine

Arginine participates in the cycle of transamination and excretion of the final nitrogen from the body, that is, the product of the breakdown of spent proteins. The ability of the body to synthesize urea and remove protein slags depends on the power of the cycle (ornithine — citrulline — arginine).

After the discovery of the biological effects of arginine in 1998, scientists F.Mured, R. Ferchgott and L. Ignarro were awarded the Nobel Prize in Medicine, however, this discovery in no way confirms the effectiveness of arginine-based supplements.

Arginine in food products

Arginine is a conditionally essential acid, because it can be synthesized in the human body. However, the body cannot produce enough arginine, and some of it must come from food or sports nutrition. In bodybuilding, arginine is used in significant doses, since several other goals are pursued.

Arginine is found in products: cottage cheese, cheese, and other dairy products, meat, seafood, cereals, nuts, etc.
