NOW Foods L-Histidine 600mg 60 Veg Capsules

NOW® L-Histidine supplies 600 mg of free-form L-histidine in each vegetarian capsule. Histidine is an essential amino acid that the body uses for several important purposes: it is critical for normal brain function, it serves as a precursor to histamine (a compound involved in immune responses and nerve signaling), and it is a building block for carnosine and other tissue-protective compounds. It also helps maintain the myelin sheaths that insulate nerve cells. Through these roles, histidine supports brain, nervous-system and immune health.*
