Documented Uses
- Indicated for use as a supplement to intravenous solutions given for total parenteral nutrition (TPN), to maintain chromium serum levels and to prevent depletion of endogenous stores and subsequent deficiency symptoms.
- Chromium compounds are both absorbed by the lung and the gastrointestinal tract. Oral absorption of chromium compounds in humans can range between 0.5% and 10%, with the hexavalent (VI) chromium more easily absorbed than the trivalent (III) form. Absorption of chromium from the intestinal tract is low, ranging from less than 0.4% to 2.5% of the amount consumed. Vitamin C and the vitamin B niacin is reported to enhance chromium absorption. Most hexavalent Cr (VI) undergoes partial intragastric reduction to Cr (III)
- Absorbed chromium is excreted mainly in the urine, accounting for 80% of total excretion of chromium; small amounts are lost in hair, perspiration and bile. Chromium is excreted primarily in the urine by glomerular filtration or bound to a low molecular-weight organic transporter.
- Absorbed chromium is distributed to all tissues of the body and its distribution in the body depends on the species, age, and chemical form. Circulating Cr (III) following oral or parenteral administration of different compounds can be taken up by tissues and accumulates in the liver, kidney, spleen, soft tissue, and bone.
- Excretion of chromium is via the kidneys ranges from 3 to 50 μg/day. The 24-hour urinary excretion rates for normal human subjects are reported to be 0.22 μg/day.
- In the blood, 95% of chromium (III) is bound to large molecular mass proteins, such as transferrin, while a small proportion associates with low molecular mass oligopeptides. Serum chromium is bound to transferrin in the beta globulin fraction.
