Nickel is a mineral element with the atomic number of 28.
Nickel interacts with cobalt, vitamin C, vitamin E, vitamin B12 and vitamin B15. Nickel (Ni) and
Cobalt (Co) are associated trace elements and considered essential
to human health. While a cobalt and vitamin B12 relationship is well
documented, a similar, but less documented affiliation applies to
nickel and vitamin C. Also less documented is the control nickel
and cobalt exert over the muscular walls of the body's
arteries. Nickel specifically affects the left coronary artery,
resulting in vasodilation with low levels, and vasoconstriction with
high levels, while cobalt exerts the same vasodilatation /
vasoconstriction effect on the right coronary artery.
Nickel and vitamin C
share a common antagonist; vitamin E.
The association of nickel to vitamin C is similar to the one of
cobalt to vitamin B12 as far as excess and deficiency symptoms and
their interaction with other nutrients is concerned. For instance,
iron deficiency (anaemia) is often found in the presence of low nickel, and it is a well-known fact that vitamin C assists in iron absorption. Both vitamin C and nickel can also be beneficial for cirrhosis of the liver, hypoadrenalism and can improve insulin production in diabetics.
The cell receptors of nickel and
are neurologically linked to the spinal segment T4, whereby both,
its alignment, and various nutritional factors control the ratio of
nickel and cobalt. Alignment problems of T4, or nutritional
imbalances involving nickel,
vitamin B12 and
vitamin B15 can either result in
localised physical discomfort, or they can trigger cardiac,
cerebral, emotional and/or anxiety-problems due to blood flow
changes to the heart or brain through their respective vasoconstrictive or vasodilating changes.
of nickel is less than 10%, with the kidneys controlling the
retention or elimination of nickel, however most of it is eliminated
in faeces, some in urine, and a small amount through sweat.
Nickel toxicity is
usually not a problem unless several grams are ingested from
non-dietary sources or there is a natural tendency to retain too
much nickel, which could lead to asthma, angina an/or other cardiac
symptoms as a result of nickel interfering with vitamin E activity.
Nickel is quite toxic in its gaseous form of nickel carbonyl, and it
has the potential to cause cancer of the sinuses, throat and lungs
when insoluble nickel compounds are inhaled for long periods of
time. This does not apply to soluble nickel compounds such as
chloride, nitrate, or sulphate. Once someone is sensitised to nickel
from an allergic reaction to nickel-containing materials, subsequent
contact will have to be avoided as it will continue to produce these
effects. Skin reactions such as itching, burning, redness or other
rashes are the most common symptoms with nickel sensitivity, however
asthma attacks are another, but less frequent possibility in some
Nickel is a trace
element that has been linked to skin allergies or dermatitis. Nickel
is found in coins, costume jewellery, dental materials,
eyeglass frames, hair clips, pins, scissors and some kitchen
appliances. Regular contact with these nickel products may allow
some absorption into the body. Allergic dermatitis from nickel
products is not at all uncommon, however of the approximately 10 mg in the body,
significant amounts of nickel are found in RNA and DNA where it
interacts with these nucleic acids.
Most of plasma nickel is a
constituent of the circulating proteins nickeloplasmin and albumin,
and it is also thought to be a factor in hormone, lipid and cell
membrane metabolism. Insulin response is increased after ingesting
nickel, which may be related to its activation of enzymes associated
with the breakdown or utilization of glucose.
