What L-Arginine does
L-arginine is an amino acid that the body also synthesizes (from citrulline), mainly in the kidneys. Some experts suggest that taking arginine in supplement form may enhance exercise and athletic performance in several ways: some arginine is converted to nitric oxide, a vasodilator that can increase blood flow and the delivery of oxygen and nutrients to skeletal muscle, and this increased vasodilation may speed removal of metabolic waste products related to muscle fatigue. Arginine also serves as a precursor for creatine synthesis and may increase secretion of human growth hormone. However, the research to support supplemental arginine as a performance enhancer is limited and conflicting, and doses of 2–20 g/day appear to have little to no effect on anaerobic or aerobic exercise performance. One review of 54 clinical studies concluded that supplemental arginine provided little or no enhancement of athletic performance and did not improve recovery from exhaustion. Overall, arginine supplementation's ability to enhance strength, improve exercise or athletic performance, or promote muscular recovery after exercise has little scientific support. — per NIH Office of Dietary Supplements; not medical advice.
Food sources of L-Arginine
L-arginine is found in many protein-containing foods, especially animal products and nuts, and typical dietary intake is about 4–5 grams per day. — per NIH Office of Dietary Supplements; not medical advice.
Can you get too much L-Arginine?
Most study results suggest that up to 9 g/day of arginine for several days or weeks is safe and well tolerated. At doses of 9–30 g/day, the most commonly reported adverse reactions are gastrointestinal discomfort, such as diarrhea and nausea, and slightly reduced blood pressure. The safety of taking high-dose arginine supplements for more than 3 months is not known. — per NIH Office of Dietary Supplements; not medical advice.
