Histidine is an essential amino acid, in other words one that must be supplied through the diet in order for the body to function correctly. It is only essential for newborns, who obtain their supply in breast milk. Histidine enables copper and zinc binding, two important trace elements in the central nervous and immune system. This amino acid aids in the production of red and white blood cells, in skin regeneration following solar damage, in the elimination of heavy metals, in nerve protection, and in limiting allergies.
