Through its interaction with insulin receptors, insulin provides cells with glucose for energy and helps maintain blood glucose within a narrow range of concentrations. Insulin binds to insulin receptors on the surface of cells, activating the receptors and stimulating glucose uptake by cells. Insulin is secreted by specialized cells in the pancreas in response to increased blood glucose levels, such as after a meal. Trivalent chromium has been proposed to be the cofactor for a biologically active molecule that could enhance the effects of insulin on target tissues. In the acidic environment of the stomach, hexavalent chromium can be readily reduced to trivalent chromium by reducing substances present in food, which limits the ingestion of hexavalent chromium (3-5).

Hexavalent chromium is highly toxic and is classified as a human carcinogen when inhaled (2). Hexavalent chromium is derived from trivalent chromium by heating at alkaline pH and is used as a source of chromium for industrial purposes. Another common and stable form of chromium in the environment is hexavalent chromium (Cr 6+). The essentiality of trivalent chromium is questioned, and its presumed function in the body remains poorly understood. The most stable oxidation state of chromium in biological systems is trivalent chromium (Cr 3+), which forms relatively inert complexes with proteins and nucleic acids (1). (More information)Ĭhromium was first discovered in 1797. (More information)įew adverse events have been reported with chromium supplementation. (More information)Ī well-balanced diet that includes fruit, vegetables, meat, fish, and grains should easily cover dietary needs of chromium.

Randomized controlled trials have failed to provide any evidence of benefits of chromium supplementation in the prevention or treatment of impaired glucose tolerance and type 2 diabetes mellitus.

In 2001, the US Institute of Medicine set the adequate intake ( AI) of chromium at 20-35 μg/day for adults. The lack of an accurate measure of chromium nutritional status prevents the identification of individuals who may be susceptible to chromium deficiency. Potential chromium deficiency cases have been associated with symptoms resembling diabetes mellitus: impaired glucose tolerance and increased insulin requirements. Chromodulin may be able to potentiate the action of insulin, hence improving tissue sensitivity to insulin and facilitating glucose transport into cells. Trivalent chromium has been proposed to be the cofactor for an oligopeptide called chromodulin. The predominant chromium form in the body is trivalent chromium (Cr 3+), which may play a role in normal insulin function.
