Chromium influences carbohydrate, fat, and protein (protein) metabolism as an essential component of the so-called glucose tolerance factor (GTF). Influence on insulin action – improvement of glucose tolerance Glucose tolerance factor represents the biologically active form of chromium. Its exact structure has not yet been clearly elucidated. The GTF appears to consist of one or … Chrome: Functions
Interactions of chromium with other macro- and micronutrients (vital substances): Vitamin C In animals, it can be shown that simultaneous administration of vitamin C increases the absorption of chromium. Iron Chromium competes with iron for a binding site on the iron transport protein, transferrin. Nevertheless, supplementing older men’s diets with 925 µg chromium/day for 12 … Chrome: Interactions
There have been three reports of patients in intensive care units who were fed parenterally (by vein) for prolonged periods without chromium supplementation, who then developed insulin resistance and impaired glucose metabolism. No symptoms attributable to chromium deficiency have yet been noted in individuals who are able to eat a normal diet.
Risk groups for deficiency include individuals with Long-term parenteral nutrition without chromium supplementation. Diabetes mellitus – according to studies, chromium supplementation improved glucose tolerance (fasting serum glucose level ↓, serum insulin level ↓) and lowered total cholesterol and triglyceride levels, while HDL cholesterol levels increased
The United Kingdom Expert Group on Vitamins and Minerals (EVM) last evaluated vitamins and minerals for safety in 2003 and set a so-called Safe Upper Level (SUL) or Guidance Level for each micronutrient, provided sufficient data were available. This SUL or Guidance Level reflects the safe maximum amount of a micronutrient that will not cause … Chromium: Safety Assessment
Chromium was not included in the National Consumption Survey II (2008). Regarding the intake of chromium in the German population, data exist only from a study by Anke et al. in 1998. Regarding the supply situation, it can be stated: On average, men take 84 µg and women 61 µg chromium per day to themselves … Chrome: Supply Situation
The intake recommendations (D-A-CH reference values) of the German Nutrition Society (DGE) presented below are aimed at healthy people of normal weight. They do not refer to the supply of sick and convalescent people. Individual requirements may therefore be higher than the intake recommendations of the DGE (e.g., due to dietary habits, consumption of stimulants, … Chromium: Intake
