L-Histidine Amino Acid, 500 mg Swanson AjiPure L-Histidine 500 mg

The essential amino acid histidine is perhaps best known as a precursor to histamine, a critical component of a healthy immune system. However, histidine does much more. It plays a key role in the absorption of iron. It is essential for the formation of the most productive antioxidant, superoxide dismutase (SOD). It even facilitates the transport of trace elements within the body. Although most people consume a significant amount of histidine in their diet, doctors recommend supplements for those in need of increased levels.
