L-histidine* is an essential
amino acid that cannot be formed by other nutrients, and must
be in the diet to be available to the body.
Most often recognized as a precursor to the allergy symptom
producing hormone histamine, both histidine and histamine have
essential roles in the body beyond tormenting allergy sufferers.
Histamine is well known for its role in stimulating the inflammatory
response of skin and mucous membranes such as those found in
the nose - this action is essential in the protection of these
barriers during infection.
Histamine also stimulates the secretion of the digestive enzyme
gastrin. Without adequate histamine production healthy digestion
can become impaired. Without adequate L-histidine stores, the
body cannot maintain adequate histamine levels.
Less well known is that L-histidine is required by the body
to regulate and utilize essential trace minerals such as copper,
zinc, iron, manganese and molybdenum.
L-histidine is essential in forming many metal bearing enzymes
and compounds, examples being the antioxidant super oxide
dismutase, the iron storage protein ferritin, the
iron uptake regulation protein -FUR, the copper storage
and iron metabolism cofactor cerulplasmin, red blood cell
hemoglobin, the toxic metal storage protein metallothionein,
and the cysteine regulating enzyme cysteine dioxygenase -
to name but a few important enzymes dependent on L-histidine
being available for formation and function.
Metals such as zinc, copper and nickel are transported by
binding with L-histidine, and such binding appears essential
for rapid excretion of excess metal.
Toxic metals such as mercury, lead, cadmium, and threatening
excesses of essential minerals zinc and copper stimulate the
rapid formation of metallothionein inside cells of the brain,
liver, and kidneys.
Metallothionein is a molecule designed to store metals in
such a way as to prevent uncontrolled oxidation reactions - protecting
the normal workings of the cell. Metallothionein requires both
L-cysteine (usually derived from available glutathione stores)
and L-histidine to be formed.
Persons contaminated with heavy metals, suffering from chronic
seasonal allergies, or following a low histidine diet are most
susceptible to body depletion of adequate histidine stores -
creating the possibility of mineral-enzyme deficiencies and dysregulation.
Depletion of body stores of L-histidine might be best recognized
by dysfunction of L-histidine dependent compounds, and low blood
plasma concentrations of the amino acid.
High blood serum levels of iron have been experimentally caused
in humans by a diet low in L-Histidine.
Intolerance of sulfur bearing foods like garlic and broccoli
along with elevated blood plasma L-cysteine levels indicate inactivation
of the L-Histidine and iron dependent enzyme cysteine dioxygenase.
As with most free form amino acids, L-histidine absorption
is best when taken between meals without food and without accompanying
If you are taking other amino acids such as those found in
our Defense Formula, L-Histidine should be taken at the same
time as these.
