Histidine is an amino acid that is used to develop and maintain
healthy tissues in all parts of the body, particularly the myelin
sheaths that coat nerve cells and ensure the transmission of
messages from the brain to various parts of the body. It may be
useful for treatment of mental disorders as well as certain types
of sexual dysfunction.
Histidine levels in the body must be balanced to ensure good mental
and physical health. High levels of this amino acid have been
linked to the presence of psychological disorders such as anxiety
and schizophrenia, while low levels of histidine are thought
contribute to the development of rheumatoid arthritis and the type
of deafness that results from nerve damage. Taking
histidine supplements may help relieve symptoms of
rheumatoid arthritis.
Histidine is important to normal sexual functioning, because it
gets converted into histamine, a chemical needed to stimulate
sexual arousal. When taken together with vitamin B3 (niacin) and
vitamin B6 (pyridoxine), histidine can increase sexual pleasure by
boosting histamine levels in the body. Histamine is also needed to
help the immune system know when the body is experiencing an
allergic reaction, and for the production of gastric juices needed
for normal digestion.
Research suggests that hsitidine also acts as a natural detoxifier,
protecting against radiation damage, and removing heavy metals from
the system. It may even help prevent the onset of AIDS istidine is
crucial to the production of both red and white blood cells.
Like other amino acids, histidine is found in many high-protein
foods, such as meat and dairy products, as well as grains such as
rice, wheat, and rye. It is not certain if histidine is an
essential or non-essential amino acid ost health experts agree
that, although the body manufactures its own histidine, it is
fairly easy for natural supplies to run short. The chronically ill,
post-surgery, or arthritic individual may wish to consider
supplementation with this amino acid. Histidine is available in
both capsule and powder forms, as well as in combination amino acid
formulas.
Because it has a proven effect on the central nervous system and
histamine production, people with manic (bipolar) depression should
not take supplemental histidine without first consulting their
physician. Anyone with liver or kidney disorders should not take
histidine without first consulting with a licensed health care
provider. Taking any one amino acid supplement may cause levels of
nitrogen in the body to become imbalanced, as well as disrupt the
Krebs cycle by which toxins are eliminated from the liver and
kidneys.
