L-Histidine is an essential amino acid that is required for the production of HISTAMINE. L-Histidine is a semi-essential amino acid needed for growth and tissue repair. L-Histidine is important for maintenance of myelin sheaths that protect nerve cells and is metabolized to the neurotransmitter histamine. Histamines play many roles in immunity, gastric secretion, and sexual functions. L-Histidine is also required for blood cell manufacture and protects tissues against damage caused by radiation and heavy metals.
