Most often recognized as a precursor to the allergy symptom producing hormone histamine, both histidine and histamine have essential roles in the body beyond tormenting allergy sufferers. Histamine is well known for its role in stimulating the inflammatory response of skin and mucous membranes such as those found in the nose - this action is essential in the protection of these barriers during infection.
Histamine also stimulates the secretion of the digestive enzyme gastrin.
Without adequate histamine production healthy digestion can become impaired. Without adequate L-histidine stores, the body cannot maintain adequate histamine levels. Less well known is that L-histidine is required by the body to regulate and utilize essential trace minerals such as copper, zinc, iron, manganese and molybdenum. Metals such as zinc, copper and nickel are transported by binding with L-histidine, and such binding appears essential for rapid excretion of excess metal. Toxic metals such as mercury, lead, cadmium, and threatening excesses of essential minerals zinc and copper stimulate the rapid formation of metallothionein inside cells of the brain, liver, and kidneys.
