What is Histidine?
Histidine is an essential amino acid that is crucial for growth, tissue repair, and the production of histamine, a neurotransmitter involved in immune response, digestion, and sleep-wake cycles. Because the body cannot produce histidine, it must be obtained through the diet.
Benefits of Histidine
Protein Synthesis: Vital for the production and maintenance of proteins in the body.
Histamine Production: Essential for producing histamine, which is important for immune response, gastric acid secretion, and neurotransmission.
Hemoglobin Formation: Plays a role in forming hemoglobin, the protein in red blood cells that carries oxygen throughout the body.
Tissue Repair: Important for the growth and repair of tissues.
Joint Health: Helps maintain the myelin sheaths that protect nerve cells and is involved in the production of collagen, which is necessary for healthy joints and skin.
Daily Recommended Value (DRV) for Histidine
The DRV for Histidine is approximately 14 mg per kilogram of body weight per day. For an average adult weighing 70 kg, the daily requirement would be:
14 mg x 70 kg = 980 mg per day
