Histidine is an essential amino acid that's important for protein synthesis, hormone production, and other bodily functions. It's found in many protein-rich foods, including meat, fish, eggs, soy, beans, nuts, and whole grains.
Function
Protein synthesis: Histidine is a component of proteins and is especially important in the active site of enzymes
Hormone production: Histidine is a precursor for hormones like thyrotropin-releasing hormone
Metabolism: Histidine is involved in metabolites that affect the immune system, neurotransmission, renal function, and gastric secretion
Anti-inflammatory: Histidine has anti-inflammatory, anti-oxidant, and anti-secretory functions
Hair health: Histidine can help improve the strength and elasticity of hair
Other information
