Description
Summary - Chromium (Cr0) is an ubiquitous trace metal. The predominant chromium form in the body is trivalent chromium (Cr3+), which may play a role in normal insulin function. (More information)
- Trivalent chromium has been proposed to be the cofactor for an oligopeptide called chromodulin. Chromodulin may be able to potentiate the action of insulin, hence improving tissue sensitivity to insulin and facilitating glucose transport into cells. (More information)
- Potential chromium deficiency cases have been associated with symptoms resembling diabetes mellitus: impaired glucose tolerance and increased insulin requirements. (More information)
- The lack of an accurate measure of chromium nutritional status prevents the identification of individuals who may be susceptible to chromium deficiency. In 2001, the US Institute of Medicine set the adequate intake (AI) of chromium at 20-35 mcg/day for adults. (More information)
- 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. (More information)
- A well-balanced diet that includes fruit, vegetables, meat, fish, and grains should easily cover dietary needs of chromium. (More information)
- Few adverse events have been reported with chromium supplementation. (More information)
