L-Arginine Base refers to the basic form of the amino acid L-Arginine. L-Arginine is a semi-essential amino acid, meaning that the body can normally produce it itself, but in certain situations there may be an increased need. The term “base” refers to the chemical structure of the amino acid. In its basic form, L-arginine exists as a free amino acid, without specific binding to other molecules. L-Arginine Base is used in dietary supplements to provide a pure and concentrated form of L-Arginine. L-arginine is a precursor of nitric oxide (NO), an important messenger in the body. It plays a crucial role in regulating blood flow, vasodilation and supporting the cardiovascular system. L-Arginine Base is often used by athletes, fitness enthusiasts and people who want to improve their physical performance.
