  • Effectively intensifies effect of muscle pump
  • Enhances blood flow and nutrition in muscles
  • Stimulates nitric oxide synthesis in organism
  • Enhances cardiovascular system functions
  • Protects liver and supports its functions
  • Improves toxin neutralisation in organism
  • Increases muscle resistance to tiredness
  • Helps to improve regenerative capacity

BioTech L-Arginine is a dietary supplement containing pure, high-quality L-arginine in the form of comfortable capsules. The preparation naturally increases nitric oxide levels, that way making the sensation of a muscle pump stronger and enhancing the nutrition of muscle tissue. Moreover, it has a beneficial effect on the circulatory system and supports liver functions.

L-Arginine (2-amine2-amino-5-guanidinovaleric acid) is an endogenous amino acid that performs many functions in the human organism. It is a precursor in the synthesis of numerous compounds essential for the process of many biochemical conversions, such as those of nitric oxide, urea, ornithine, creatine, glutamate, and proline.

Arginine was first isolated in 1886 from lupine sprouts, and a few years later its presence was also discovered in animal tissues. In the 1930s, it was demonstrated that the amino acid plays a crucial role in the urea cycle, thanks to which it is possible to remove toxic ammonia from the organism. It was also discovered that L-arginine has the function of a substrate in the production of carnitine and creatine.

L-arginine is an amino acid that can be synthesised by the organism but it is becoming more and more widely believed that it is essential for the normal functioning of the body and should be delivered with food as well, especially in the case of injuries or diseases.

Nitric oxide precursor
L-Arginine is a crucial component on the synthesis pathway of nitric oxide (NO), which helps to dilate blood vessels. As a source of endogenous NO, the amino acid affects the relaxation of smooth muscles and regulates the resistance of vessel walls, thanks to which it supports the functioning of the circulatory system and can prevent the development of hypertension and other cardiovascular system disorders.

As NO helps to relax vascular smooth muscles, it can increase the amount of blood transporting oxygen and nutrients that reaches working muscles. As a result, the organism’s capacity increases and it is possible to train more intensively; an interesting and visible effect are also full, turgid muscles.

Many scientific tests demonstrated that reduced NO synthesis can be a factor increasing the risk of hypertension, the coronary heart disease, or atherosclerosis. Supplementation with L-arginine can enhance the functioning of the circulatory system, and not only through its effect on NO synthesis. As a basic amino acid, L-arginine also helps to regulate intracellular and blood pH, as well as affects the polarisation of endothelial cell membranes.

As the organism ages, the synthesis of NO decreases, which contributes to the development of disorders of the vascular endothelium. Because of that, supplementation with arginine among seniors is fully justified, even more so because it has been observed to have a positive effect on the cardiovascular system.

Support for liver functions
L-Arginine affects the normal functioning of the liver, where it plays an important role in the urea cycle, thanks to which it is possible for the organism to remove toxic ammonia formed as a result of the utilisation of amino acids that weren’t used by the body. Because of that, L-arginine is used as an aid in the case of liver treatment connected with urea cycle disorders, ammonia poisonings, or asthenia.

Beneficial for nervous system
NO also plays an important role in regulating the resistance of cerebral blood vessels. Administering L-arginine in the case of insufficient NO levels in the vessels has helped to stimulate its synthesis, that way improving the survival of brain cells in the case of focal brain ischaemia. It can mean that L-arginine performs a protective function when it comes to hypoxia and damage induced by reperfusion.

NO also plays a role of a neurotransmitter in the brain and the peripheral nervous system, as well as enhances the immune system.

To sum up, BioTech L-Arginine is a dietary supplement that efficiently increases L-arginine levels in the organism. The preparation supports the organism’s regeneration, helps to neutralise toxic substances, and enhances the functioning of the circulatory system, thanks to which it improves the capacity and performance of the body. It is recommended not only for physically active people, who dream about the powerful effect of a muscle pump, but also for those who want to enhance the functioning of their cardiovascular and immune systems.

Arginine is an exogenous amino acid, it is a component of dietary proteins, not always synthesized in the human body in necessary quantity, so it is necessary to deliver it in the form of synthetics. It takes part in the biosynthesis agmatine, creatine and nitrogen oxides. The use of supplements containing arginine before workout increases the exercise capacity (strength, endurance). Used after considerable effort intensifies the transfer of energy and building compounds and intensifies the process of recovery. Used at bedtime in combination with lysine and ornithine enhances the synthesis of growth hormone. takes part in the intrasystemic synthesis of creatine. Arginine (as a precursor of ornithine) is involved in the urea cycle, increases the flow of blood in the circulatory system, increases sexual potency (in a short time after application). It affects the body's immunity preventing infections, and lowers blood pressure. In supplements – usually as alpha-ketoglutarate.
