L-arginine is a semi-essential amino acid found primarily in protein-rich foods. In certain individual circumstances, particularly during periods of stress, the body may not be able to produce all semi-essential amino acids in their optimal form. In such cases, L-arginine should be specifically supplied to the body through diet or supplements. L-arginine is found predominantly in protein, particularly in peanut protein (11%), and is also widely distributed in free form in plant-based foods. It is a major component of collagen, elastin, hemoglobin, insulin, and glucagon.

L-Arginine powder contains 100g of L-arginine. Large amounts of L-arginine are found in cheese, eggs, milk, and especially meat. As a semi-essential amino acid, its intake should be increased under certain stressful situations, such as during training or under stress. L-arginine is important for muscle metabolism and plays a key role in the storage, transport, and excretion of nitrogen. Creatine, one of the energy-rich compounds in muscles, is produced from L-arginine. L-arginine also plays an important role in liver metabolism. As a source of nitric oxide (NO), this amino acid, along with L-lysine, is crucial for lymphocyte proliferation. Therefore, L-arginine has a strengthening effect on the body's immune system and can positively influence wound healing.

L-arginine is not of animal origin and is produced by fermentation or protein hydrolysis. Fermentation is the industrially carried out refinement of plant-based raw materials through enzymatic processes. The gelatin used in the hard gelatin capsules is BSE/TSE-tested pharmaceutical gelatin.
