• Drug Groups: approved; nutraceutical
• Description: An essential amino acid that is required for the production of histamine. [PubChem]
• Indication: The actions of supplemental L-histidine are entirely unclear. It may have some immunomodulatory as well as antioxidant activity. L-histidine may be indicated for use in some with rheumatoid arthritis. It is not indicated for treatment of anemia or uremia or for lowering serum cholesterol.
• Pharmacology: Is found abundantly in hemoglobin; has been used in the treatment of rheumatoid arthritis, allergic diseases, ulcers and anemia. A deficiency can cause poor hearing.
• Toxicity: ORL-RAT LD₅₀ > 15000 mg/kg, IPR-RAT LD₅₀ > 8000 mg/kg, ORL-MUS LD₅₀ > 15000 mg/kg, IVN-MUS LD₅₀ > 2000 mg/kg; Mild gastrointestinal side effects.
• Affected Organisms: Humans and other mammals
• Absorption: Absorbed from the small intestine via an active transport mechanism requiring the presence of sodium.
