L-Arginine

                                   
L - Arginine is a semi-essential amino acid. Its main function is to synthesize nitric oxide to dilate blood vessels, participate in the urea cycle to metabolize ammonia, and also to synthesize proteins and creatine. It is crucial for maintaining cardiovascular function and nitrogen balance. As a nutritional fortifier, it can be added to food to enhance its nutritional value; it can promote the synthesis of collagen, enhance the tissue repair ability at the wound site, and at the same time, its regulatory effect on the immune system also helps prevent wound infection and accelerate the healing speed of wounds; it plays an important role in the generation and maturation of male sperm. It can increase sperm quantity and improve sperm vitality. For some cases of infertility caused by sperm quality problems, supplementing L - Arginine may have certain therapeutic effects.
