L-Arginine is considered to be a miracle amino acid because it produces massive amounts of nitric oxide. A Nobel Prize was awarded to Louis Ignarro and his team on nitric oxide research. Nitric oxide is extremely important in the human body because it allows the endothelial lining of arteries to relax thus increasing circulation. By increasing circulation, you increase oxygenation. Supplementing L-arginine creates greater amounts of nitric oxide which changes your arteries from being sticky like Velcro to being slippery like Teflon. Research has found that combining L-citrulline increased the half-life of L-arginine in the body prolonging its effects.
L-Arginine Supplement Benefits for Men and Women
L-arginine is a protein amino acid present in the proteins in all life forms. It is classified as a semi-essential amino acid which means that the body can synthesize sufficient L-arginine to meet the needs of the body. Some stress conditions can place an increase demand on the body for the synthesis of L-arginine which include trauma, sepsis and burns. L-arginine is a precursor in the formation of nitric oxide, creatine, polyamines, L-glutamate, L-proline, agmatin (a possible neurotransmitter in the brain) and tuftsin, believed to be an immunomodulator. L-arginine can be found in vegetable juices and fermented foods, such as miso and yogurt, soy protein and other plant proteins. Research has shown that supplemental L-arginine may have anti-atherogenic, antioxidant and immunomodulatory actions as well as wound-repair activity. Nitric oxide formed from supplemental L-arginine inhibits mononuclear cell adhesion, platelet aggregaton and proliferation of vascular smooth muscle. L-arginine has been reported to increase the quantity and cytotoxic activity of natural killer cells to aid the immune system. L-arginine, administered in high enough dosages, stimulates the pituitary release of growth hormone and prolactin along with the pancreatic release of glucagons and insulin. L-arginine has shown promise in the treatment of cardiovascular disease (including atherosclerosis, hypertension, hyperlipidemia and angina pectoris), some forms of male infertility and some kidney disorders. Some testing indicates that L-arginine may have an effect on endothelial cells that could help to inhibit cardiovascular disease.
L-Arginine Supplement Research
In a double blind, placebo-controlled study of 22 subjects with stable angina, supplemental L-arginine significantly improved exercise capacity and resulted in a 70% reduction in angina attacks in another study. Subsequent studies have shown that L-arginine improves sperm count and motility. L-arginine has shown promise in helping interstitial cystitis and improving kidney function. L-arginine improves nitrogen balance and thus reduces protein catabolism. It should be noted that L-arginine is not recommended for people with herpes, asthma, recent heart attack, low blood pressure, heart arrhythmias, and other allergies to L-arginine. More and more patients are realizing the benefits of nutrition and with medical research are validating what chiropractors have known for years.
