One supplement that has attracted considerable clinical interest is chromium (Cr). However, routine use of Cr in subjects with diabetes is not currently recommended. In part, the controversy surrounding Cr supplementation stems from the lack of definitive randomized trials, the lack of "gold standard" techniques to assess glucose metabolism in the studies reported, the use of differing doses and formulation , and the study of heterogeneous study populations. As such, conflicting data has been reported that has contributed greatly to the confusion among healthcare providers concerning Cr supplementation. In order to provide a comprehensive clinical evaluation of Cr, we conducted a randomized, double-blinded, placebo-controlled trial in subjects with Type 2 diabetes. Individuals had baseline measures consisting of oral glucose tolerance testing, body fat and adiposity assessed, and then used established techniques to assess insulin sensitivity with hyperinsulinemic-euglycemic clamps. Individuals were evaluated for 6 months at which time repeat testing was done.
