Trace element chromium · Briefly

Chromium was first discovered in 1797 by French chemist Nicolas-Louis Vauquelin. In 1955, American scientists Mertz and Schwarz studied the pathological model of necrotizing hepatic degeneration in rats caused by dietary deficiency of vitamin E and factor III, and performed glucose load tests on rats with the latent stage of the disease, and found that the rate of excess blood sugar clearance in rats fed the test diet was greatly reduced (2.8% per minute in the experimental group vs. 4.0% in the control group), and this impaired glucose metabolism can be restored by supplementation with factor III.
