Histidine is an essential amino acid, meaning the body cannot produce it and it must be obtained through diet. It serves as a precursor for numerous critical compounds and supports vital physiological functions:

• • Supporting immune function as a precursor to histamine, which regulates immune responses, allergies, and inflammation

  • Promoting tissue repair and growth through its role in protein synthesis and cellular regeneration

  • Maintaining metabolic balance by assisting in enzyme function, nutrient metabolism, and pH regulation

  • Protecting neural health by contributing to the production of myelin sheaths (nerve protectors) and neurotransmitters

Rich dietary sources of histidine include: meat, poultry, fish, dairy, eggs, soybeans, beans, nuts, seeds, and whole grains.

Low histidine levels may weaken immune defenses, impair wound healing, disrupt metabolic processes, and contribute to fatigue or neurological issues.
