The Active Ingredient Is: L-Histidine (AjiPure)

L-Histidine is an essential amino acid used by the body in a range of metabolic processes and as a precursor to histamine. It supports normal physiological functions including immune support and antioxidant defence.

This formulation uses pharmaceutical-grade AjiPure L-Histidine enclosed in a vegetarian capsule, with rice flour and calcium laurate as excipients. It is vegan and designed for a reliable amino acid supply to support overall wellness.

What Does L-Histidine Do?

Scientific research suggests L-Histidine participates in histamine production and supports immune function, while also contributing to antioxidant defence through pathways like SOD formation and aiding iron metabolism.

Dr. Reedy from the University of Colorado found that histidine can be involved in iron uptake and antioxidant processes, aligning with EFSA-style understanding of amino acid roles in normal physiology.
