A trace element purported to improve insulin sensitivity it is sold as Chromium Picolinate, Chromium Propionate and chelated in Chromium yeast. Some studies in humans indicated positive response to chromium supplementation with improved glucose tolerance in insulin resistant patients. Limited trials in horses yielded conflicting results with slightly lowered peak insulin response to an oral starch challenge test in one experiment, and no significant effect in another larger longer trial. Further research is needed to determine whether or not Chromium has value in the management of Insulin Resistance or potentially Laminitis in horses. Chromium deficiency has never been recorded in horses indicating that normal dietary intake is likely sufficient. Meanwhile Chromium is heavily promoted as enhancing athletic performance, improving health, and reducing insulin resistance with scant if any justification.
