Chromium(III) picolinate (CrPic3) is a chemical compound sold as a nutritional supplement to treat type 2 diabetes and promote weight loss. This bright-red coordination compound is derived from chromium(III) and picolinic acid. Small quantities of chromium are needed for glucose utilization by insulin in normal health, but deficiency is extremely rare and has only been observed in people receiving 100% of their nutrient needs intravenously, i.e., total parenteral nutrition diets. Chromium has been identified as regulating insulin by increasing the sensitivity of the insulin receptor.

As such, chromium(III) picolinate has been proposed as a treatment for type 2 diabetes, although its effectiveness remains controversial due to conflicting evidence from human trials.
