Chromium picolinate (Cat No.: R023295) is a coordination complex containing trivalent chromium chelated by three picolinic acid ligands. This bright reddish-purple compound is water-insoluble but bioavailable when ingested, allowing chromium to participate in glucose and lipid metabolism. It is widely marketed as a dietary supplement purported to improve insulin sensitivity, support weight management, and maintain normal blood-sugar levels. Clinical evidence remains mixed; excessive doses may cause kidney or liver toxicity. In industry, chromium picolinate serves as a source of chromium for nutritional formulations.
