Supplement(trace mineral).
Chromium(III) chloride and chromium(III) sulfate have been used as dietary supplements (approved for themanufacture of foods for particular nutritional uses and in food supplements in the European Union), whereas the organic chromium(III) complexes chromium picolinate and nicotinate are not approved in the European Union but find widespread uses (e.g. in the USA) inmultivitamin, multimineral products (Riihimaki & Luotamo, 2006).They are also marketed for weight loss purposes and athletic supplements.
