Sources
Histidine is often classified as a semi-essential amino acid, which means that it is not commonly required in the diet. But periods of rapid growth may cause a histidine deficiency. Protein-rich foods like meat, poultry, fish, dairy products and other proteins are good sources of the amino acid. Histidine is crucial for muscle contractions, the iron-binding proteins responsible for oxygen transport, and ion-binding proteins such as calcium-binding, etc. Histidine is also a precursor of histamine of allergiogonic fame.
