Histidine is an essential amino acid that supports immune function, tissue repair, and nerve protection. It is a precursor to histamine, a compound important for immune responses and digestion. Found in foods such as meat, fish, and dairy, histidine is vital for maintaining healthy tissues, blood cells, and the myelin sheath around nerve cells.
Individuals with arthritis, allergies, or those experiencing symptoms of anemia could benefit from testing their histidine levels, as histidine is involved in immune response and hemoglobin formation. It’s also beneficial for people with chronic kidney disease or those following diets low in protein.
Histidine is found in high-protein foods like meats, poultry, and fish. Dairy products and eggs are also good sources. For those on a plant-based diet, soy products, beans, nuts, and seeds can provide histidine. Whole grains and some vegetables contribute as well, though in smaller amounts compared to animal proteins.
Histidine supplementation can aid in reducing inflammation, particularly beneficial for conditions like arthritis. It supports immune function and may help in alleviating allergy symptoms. Histidine is also important for maintaining healthy skin and aiding in tissue repair. For individuals with low dietary intake or specific health conditions, supplementation can help maintain adequate histidine levels for overall health.
