Country Life L-Arginine 500 mg Vegan Capsule For Immune Support provides 500 mg of L-arginine, an amino acid that teams up with methionine and glycine to help produce energy in muscles. L-Arginine is necessary for the execution of many physiological processes. Along with the energy production benefit, L-arginine also provides fundamental nourishment for immune and cardiovascular systems. Arginine is an essential nutrient for both innate and adaptive immune systems. L- Arginine can boost the activity of a particular type of immune cells, so called T cells. When the levels of L-arginine are increased the metabolism of these cells is re-organized and the cells survive longer and are more effective in fighting. L-arginine is converted in the body into a chemical called nitric oxide. Nitric oxide causes blood vessels to open wider for improved blood flow. L-arginine also stimulates the release of growth hormone, insulin, and other substances in the body. L-arginine is considered to be generally safe. It might be effective at lowering blood pressure, lower blood sugar and support athletic performance. Like many Country Life amino acids, L-Arginine 500 mg also include Vitamin B6 to aid in utilization. Wellness goals differ from person to person.
