It has been noted that no adverse effects
were observed
at intakes of 1000 - 2000 mg/day trivalent
chromium. (COMA)
Trivalent chromium is ubiquitous in nature,
occurring in air,
water, soil and biological materials.
Hexavalent chromium compounds are man-made and do
not
occur naturally in the environment.
Chromium in foods or supplements is in the
trivalent form.
Ingested trivalent chromium remains largely
unabsorbed and
is excreted via the faeces. Absorbed chromium is
mainly
excreted via urine, with only small amounts being
eliminated
in perspiration and bile.
Ingested trivalent chromium has a low level of
toxicity,
due partly to its poor absorption
In humans, deficiency has only been observed in
patients on
long-term parenteral nutrition. The symptoms
observed were
impaired glucose tolerance and glucose
utilisation, weight
loss, neuropathy, elevated plasma fatty acids,
depressed
respiratory quotient and abnormalities in nitrogen
metabolism.
