Histidine is an essential amino acid that is significant in the growth and repair of tissues. It is important for the maintenance of the myelin sheaths that protect nerve cells, and is needed for the production of both red and white blood cells.

Histidine also protects the body from radiation damage, aids in removing heavy metals from the system, and may help in the prevention of AIDS.

Histidine levels that are too high may lead to stress and even psychological disorders such as anxiety and schizophrenia, people with schizophrenia have been found to have high levels of histidine in their bodies.

Inadequate levels of histindine may contribute to rheumatoid arthritis and may be associated with nerve deafness. Methionine has the ability to lower histidine levels.

Histamine, an important immune system chemical, is derived from histidine. Histaine aids in sexual arousal. Because the availability of histidine influences histamine production, taking supplemental histidine-together with Vitamin B3 and Vitamin B6, which are required for the transformation from histidine to histamine-may help improve sexual functioning and pleasure.

Because histamine also stimulate the secretion of gastric juices, histidine may be helpful for people with indigestion resulting from a lack of stomach acid.

Caution: Persons with manic (bipolar) depression should not take supplemental histidine unless a deficiency has been identified.

Natural sources of histidine include rice, wheat, and rye.
