![]() ![]() Because only a very little chromium is absorbed while most of it is excreted, acute toxicity is unlikely to result from chromium supplementation. Only 2% of the chromium ingested in foods and supplements is absorbed while the rest is excreted without entering the blood circulation. The old values ranged from 50 micrograms to 200 micrograms for adults. ![]() The current guidelines stipulate a daily chromium uptake of 30 - 35 micrograms for adult males and 20 - 25 micrograms for an adult female. In 2001, the daily dietary requirement for chromium was lowered in the United States. ![]() This toxicity is not achievable with dietary sources of the mineral but toxicity can result from taking 1-5 – 3.3 mg/kg of oral chromium supplement. To ensure that only this amount gets through, the body has a specific transport mechanism that ferries only limited amounts of chromium into cells.Ī high concentration of chromium can cause DNA damage. The cell only needs a very small amount of trivalent chromium. Therefore, some experts do believe that chromium is essential to the body in trace amounts. On the other hand, chromium deficiency has been shown to affect glucose tolerance. This is because the biological roles of chromium are not conclusively proven. It is still unclear whether chromium is an essential mineral in the body. Hexavalent chromium is toxic and known to cause contact dermatitis. Trivalent chromium is the healthful form of the mineral. The trivalent ions of chromium are found in food and water in trace amounts. It forms a number of compounds but the most important chromium ions to human nutrition and health are the trivalent and hexavalent ions. Chromium: Essential Nutrient or Toxic Compound?Ĭhromium, the element, is a gray, steely, shinning, odorless, tasteless, hard metal. Find out why chromium is an essential supplement for diabetics and how it can help reduce blood sugar. While there is an ongoing debate over the status of chromium as an essential nutrient, experts are unanimous in the conclusion that the mineral can improve glucose tolerance, insulin action and glycemic control. ![]()
