Chromium was one of the minerals recently reviewed by the Expert Group on Vitamins and Minerals (EVM) (
http://www.foodstandards.gov.uk/multimedia/pdfs/vitmin2003.pdf). The EVM noted the reports of genotoxicity associated with chromium picolinate and excluded it from their recommendations for a Safe Upper Level for chromium. Following the publication of the EVM report, the Food Standards Agency advised that consumers should use other forms of trivalent chromium supplements.
