L(+)-Arginine L-Arg 74-79-3

L-arginine is an encoded amino acid in protein synthesis and is one of the eight essential amino acids for the human body. The body requires it to perform multiple functions. For example, it stimulates the human body to release specific chemicals such as insulin and human growth hormone. This amino acid also helps to clear ammonia from the body and promotes wound healing. The human body also needs it to produce creatine. When L-arginine is broken down, nitric oxide is produced, which can dilate vascular disease and increase blood flow. Under normal circumstances, it can produce enough L-arginine on its own. But when it is insufficient, it can be supplemented by consuming foods rich in arginine. L-arginine can be found in any protein containing food, such as meat, poultry, cheese products, fish, etc. Foods rich in arginine include almonds, walnuts, dried sunflower kernels, dark chocolate, chickpeas, cantaloupe, peanuts, green beans, hazelnuts, Brazil nuts, red meat (moderate), cashews, salmon, pistachios, soybeans, and walnuts.
