Description
"Histidine" is an essential amino acid involved in tissue repair, nerve protection, and metabolic balance. It contributes to myelin production, ensuring nerve cell insulation, while also supporting red and white blood cell formation. This amino acid participates in detoxification by binding to heavy metals and assists in cardiovascular function by regulating blood pressure. As a precursor to histamine, it influences immune responses and inflammation. Maintaining adequate histidine levels is important for cellular and metabolic health.

Synergists & Antagonists
Histidine has an antagonistic relationship with methionine, as excess methionine can reduce histidine levels. Histidine aids in the synthesis of histamine when combined with vitamin B3 (niacin) and vitamin B6 (pyridoxine).
