Arginine is a conditional amino acid, which means it can be manufactured by the body. However, in times of illness and stress, more may be needed than the body can produce. Arginine is found in foods such as dairy, meat, and fish. As a dietary supplement, "free form" L-arginine is easier for the body to utilise, as free form amino acids are already singular molecules that don't require digestion.
