Product Instruction
◆ L-histidine monohydrochloride monohydrate powder is a basic amino acid containing imidazole nucleus in the molecule. It is a semi-essential amino acid and is an essential amino acid for maintaining the growth and development of infants and young children. L-histidine is synthesized in the body via 5-monophosphate ribosyl pyrophosphate and ATP, which is a synthetic precursor of histamine, uridine diacid, carnosine and other biological substances. It has anti-ulcer effect, inhibits gastric movement and gastric acid secretion; it can still accelerate red blood cell, white blood cell production and iron intake in vivo.

Product application
◆ L-histidine monohydrochloride monohydrate powder used in nutritional supplements. The human body synthesizes slowly, which is a quasi-essential amino acid. Can be used to fortify infant foods and patient foods after surgery. When using chemical leavening agents to make bread, adding histidine, leucine, and arginine can improve the flavor.
◆ Amino acid drugs. Adjuvant treatment for peptic ulcer. It can also treat cardiovascular system disorders such as anemia and angina pectoris, aortic inflammation, and cardiac insufficiency.
