As one of the important amino acids in the body, L-arginine and other amino acids are involved in maintaining the positive nitrogen balance in the body, which can promote protein synthesis, energy metabolism, muscle production and growth and development.

In addition to the role of general amino acids, arginine also has its unique physiological functions, which play a corresponding role in maintaining the health of cardiovascular, liver and immune systems.

As a precursor for the synthesis of nitric oxide, arginine participates in the synthesis of nitric oxide in the body. NO is an important vasodilator factor in the human body, which can help dilate blood vessels and increase the elasticity of blood vessels. This function of arginine is beneficial for improving hypertension, preventing cardiovascular disease, and improving erectile dysfunction in men.

Arginine is a key substance involved in the ornithine cycle, and arginine supplementation helps convert ammonia in the blood into urea for excretion. Therefore, arginine is beneficial to people with hyperammonemia and liver dysfunction.

Arginine supplementation can promote the maturation of CD cells in the thymus, bone marrow and lymph, increase the reactivity of monocytes in the blood to antigens, and increase the activity of phagocytes, which are believed to be beneficial for improving immune function.

Arginine is also the main component of sperm protein. Supplementing arginine can promote sperm production and improve sperm quality, and has a certain effect on improving male infertility.
