The available evidence suggests favourable effects of chromium supplementation  on glycaemic control in patients with diabetes
INTRODUCTION Chromium is an essential trace mineral for carbohydrate and lipid metabolism , which is currently prescribed to control diabetes mellitus .
Results of previous systematic review s and meta-analyses of chromium supplementation and metabolic profiles in diabetes have been inconsistent .
AIM The objective of this meta- analysis was to assess the effects on metabolic profiles and safety of chromium supplementation in type 2 diabetes mellitus and cholesterol .
Chromium supplementation does not improve glucose tolerance, insulin sensitivity, or lipid profile: a randomized, placebo-controlled, double-blind trial of supplementation in subjects with impaired glucose tolerance.
Chromium supplements are thought to be the second most commonly taken nutritional supplement , used by an estimated 10 million Americans ( 1 ) . Chromium is an essential element in humans , and deficiency is associated with the development of diabetes , which was first noted in patients receiving long-term parenteral nutrition before the advent of routine chromium supplementation  ( 2,3 ) . In these patients , diabetes resolved following chromium replacement ( 2–4 ) . The dietary requirement for chromium is controversial , with the recommended daily intake in the U.S. being 0.05–0.20 μg ( 5 ) . Chromium is abundant in the environment ; however , aside from the extreme situation of unsupplemented parenteral nutrition , it has proven difficult to ascertain any clinical effects , due solely to chromium deficiency . Despite these difficulties , chromium supplements are widely promoted in the complementary health industries . There are many studies examining the effects of various forms of chromium supplementation ( rev . in 6,7 ) . These studies utilized a variety of chromium formulations , varying doses , and patients with normal glucose tolerance , diabetes , or gestational diabetes . The outcomes have been inconsistent . Some studies showed no benefit , and other studies have shown inconsistent improvements in glucose , insulin resistance , and /or lipids . The paucity of data has prompted the National Institutes of Health to release a program announcement to address the issue : “ Chromium as an adjuvant therapy
