L-Histidine is an essential amino acid, meaning the body cannot produce it on its own and must obtain it through diet or supplementation. It serves as a precursor to histamine, a compound involved in immune responses, gastric acid secretion, and neurotransmission. Research suggests that L-histidine supplementation may help support healthy hemoglobin production, which is why it has been studied in the context of anemia, particularly in individuals with chronic kidney disease. Studies also indicate potential benefits for joint comfort, as some earlier research found that people with rheumatoid arthritis tended to have lower levels of this amino acid in their blood. Commonly available in capsule form, L-histidine continues to be explored for its role in immune function and inflammatory responses, though more large-scale research is needed to fully understand its therapeutic potential.
