Histidine

Histidine is a vital amino acid, one of the building blocks that make up proteins in your body. It's considered 'essential' because your body can't produce it on its own, so you need to get it from your diet. Foods like meat, fish, dairy, and grains are rich in histidine. This amino acid plays a key role in many bodily functions. It helps in the production of hemoglobin, a protein in your red blood cells that carries oxygen throughout your body. It also contributes to the growth and repair of tissues, and is involved in the maintenance of your immune system. Moreover, histidine is a precursor to histamine, a compound that is released during allergic reactions and plays a part in your stomach acid secretion and brain function. Histidine is a small but mighty nutrient that supports your overall health and well-being.
