L-Histidine is thought to be a human essential amino acid, mainly for children. After years of development, humans begin to synthesize it, and at this time become a non-essential amino acid. L-histidine is a semi-essential amino acid that is particularly important for infants and animals. Can be used as biochemical reagents and pharmaceuticals, but also for the treatment of heart disease, anemia, rheumatoid arthritis, and other drugs. Histidine is present in bananas, grapes, meat, poultry, milk, and dairy products. In addition, histidine is also present in green vegetables, but less.
