L-Histidine is an essential amino acid and precursor to histamine, carnosine, and hemoglobin. It is critical for immune response, gastric acid secretion, and metal ion chelation. Combined with beta-alanine, it forms carnosine in muscle tissue. Deficiency affects growth, immune function, and red blood cell production.
