What is L-arginine, and what is it good for? L- Arginine is one of the 20 natural amino acid constituents of proteins. It is a precursor for the biosynthesis not only of proteins but also of nitric oxide (NO), urea (which facilitates elimination of excess nitrogen through the kidneys), polyamines, creatine and amino acids including L-proline & L-glutamate.
L- Arginine is an essential amino acid during childhood. However, it is regarded as nonessential for healthy adults because it can be synthesized in the human body from amino acids such as L-glutamate and L-glutamine. L-Arginine is often described as a conditionally essential amino acid. Humans derive L-arginine from dietary protein, biosynthesis within the body and turnover of body proteins. L-Arginine occurs in rice, soy, oat, poultry, pork, meat, fish, eggs, beans, chickpeas, nuts, seeds, buckwheat, wheat germ, granola and dairy products. Total dietary intake could be approximately 5 g/day.
Dietary L- arginine is utilized for creatine biosynthesis in the body. Creatine is crucial for energy metabolism in skeletal muscle and other organs. It is converted to a “high-energy phosphate” form, known as phosphocreatine. When bioenergy in the form of ATP dwindles, phosphocreatine is utilized as an alternative in producing ATP. Phosphocreatine is also believed to reduce acidosis in muscle cells by functioning as a buffer.
Nitric oxide (NO) is vital for cell sustenance and life. It induces blood vessel relaxation, which maintains blood flow and blood pressure, and is critical for nerve and immune health, and ultimately the optimal functional status of all other systems in the body. NO is vital in maintaining the secretion and sensitivity of the hormone, insulin, which is necessary for regulating blood sugar concentrations.
L- Arginine also plays a prominent role in the metabolism of glucose, which is essential for maintaining bioenergy and health. L-Arginine also inhibits fat synthesis and promotes the breakdown of fat. Through its ability to increase growth hormone secretion, L-arginine may stimulate muscle growth and enhance immune function. Limited L-arginine availability can selectively impair the expression of specific genes essential for a healthy cell.
In summary, studies implicate L- arginine in heart, nervous system, pulmonary, renal, liver, gastrointestinal, immune and reproductive health, tissue healing, formation of muscle mass, exercise performance and endurance.
