If you are interconnected with fitness and strength sports, or lead an active and healthy lifestyle, then the body’s replenishment of amino acids must be carried out stably and in the required amount. Amino acids are required by the entire body to carry out various physiological processes.

The amino acid l-arginine takes part in many processes and is indispensable for the body.

Donor of nitric oxide

Nitric oxide is an element that regulates the tone of arterial vessels. In the case of a lack of arginine in the body, there is a risk of high blood pressure. A nitrogen donor is essential for the integrity of muscle cells. This property contributes to the use of arginine in bodybuilding, since undigested arginine is involved in the construction of new proteins and in the formation of muscle tissue, and also reduces the level of subcutaneous fat.

Strengthens immunity

Arginine takes part in absolutely all metabolic processes, therefore, its lack leads to difficulty in resisting various infections, viral diseases and combating stress.


Arginine is involved in the elimination of the end products of nitrogen metabolism. The level of urea formation for the removal of protein breakdown products depends on the strength of the purification cycle.

Accelerates the production of growth hormone and testosterone

By adding 2 g of arginine to food in men, testosterone production can be increased. Taking arginine at night increases the production of growth hormone, which is reflected in the results in muscle gain and fat burning. Also, arginine is part of vasopressin (a peptide hormone of the pituitary gland).

Increases pumping

Due to the increase in blood circulation and a change in nitrogen balance in a positive direction, arginine enhances the result of pumping. The transport function of blood is enhanced, nutrients (creatine, sugar, water) will quickly reach muscle cells. It is also possible to achieve some venous effect.

Is a transport system for creatine

Arginine is marketed as a stand-alone supplement, but despite all its beneficial properties, it also serves as a transport system for creatine. Due to the increase in blood circulation, creatine enters muscle cells more quickly and thereby increases muscle strength and performance. Often, pre-workout supplements include arginine.

Improves erection

Arginine improves erection. Often, the use of arginine in combination with yohe imbin hydrochloride (HCL) enhances sexual function, as arginine improves blood circulation (as mentioned above).

Reduces the degree of subcutaneous fat

It has been scientifically proven that the use of arginine in conjunction with l-carnitine significantly reduces the percentage of subcutaneous fat. But not because of l-carnitine, but because of growth hormone (growth hormone), because it is considered the best endogenous (internal) fat burner.

Lowers “bad cholesterol”

“Bad cholesterol” (low density cholesterol) during oxidation can negatively affect the walls of blood vessels, but arginine is able to prevent this, which will prevent the development of atherosclerosis.

Arginine is found in food: pork, chicken fillets, salmon fillets, chicken eggs, pine nuts and walnuts, legumes, brown rice.

Dosages and contraindications

Arginine is advised to be taken before and after training, it will increase muscle nutrition and enhance the pumping (pumping effect), but if you want to increase the secretion of growth hormone, it is better to take arginine at night.

The optimal dosage will be from 1.5 g to 10 g of arginine per day. The higher the dosage, the more effective, but it is important to remember that the NO agent formed as a result of long-term use of arginine is toxic to the body. In this regard, it is not necessary to exceed the dose of 10 g per day.

It is not recommended for persons under 18 years of age for a long time. Arginine is contraindicated in pregnant and lactating women.

In case of inflammatory diseases of the musculoskeletal system, it is better to approach the use of arginine carefully and consult a doctor, since the inflammatory process can intensify.

As you can see, arginine is simply necessary during the period of weight gain and against the background of a low-carb diet. It is also used for medical purposes for the treatment of various diseases: diabetes, atherosclerosis, depression, for the healing of injuries and wounds. If you are actively exercising, then taking additional arginine is simply necessary.
