![]() 1-25Īlthough still somewhat controversial, chromium supplementation is believed by many reputable scientists and physicians to be an important tool in the war on diabetes and obesity. In contrast to hexavalent chromium, trivalent chromium is an essential micronutrient that is exceptionally well tolerated. Chromium intended for dietary supplementation is always trivalent. Although it is not recommended for ingestion, when the hexavalent form is consumed orally it is quickly converted into the harmless, bioavailable trivalent form. The hexavalent form is usually a byproduct of the metallurgy industry (for example, chrome automobile parts). Blood sugar levels remain stable when adequate chromium is present.Ĭhromium occurs in two chemical forms, called trivalent and hexavalent. Without chromium’s help, membrane portals simply fail to open. While insulin escorts glucose to “doors” in the cell membrane, chromium (probably joined with protein fragments) rings the doorbell, and perhaps holds the door open by activating receptors, while insulin ushers its precious cargo into the cell. In essence, chromium acts like a kind of doorman. As glucose piles up in the bloodstream, the pancreas produces ever-greater amounts of insulin, to little avail. Without adequate chromium, insulin evidently becomes ineffectual. When cell membranes are sensitive to the presence of insulin, they are more receptive to insulin’s efforts to usher glucose molecules out of the bloodstream and into cells, where glucose is then burned for energy. 24 High blood sugar is a damaging hallmark of diabetes. 25 It is responsible for activating insulin receptor kinase, thereby increasing insulin sensitivity. 23Ĭhromium is believed to form an integral component of so-called glucose tolerance factor, a proposed metal-protein complex sometimes referred to as chromodulin. Hyperglycemic patients given chromium after receiving a dose of glucose, or simple sugar, experienced a drop in blood sugar levels, while patients with low blood sugar, or hypoglycemia, experienced a normalization of their blood sugar levels after receiving chromium. Elevated blood sugar, or hyperglycemia, responds positively to chromium supplementation. 4-24 Chromium supplementation has the effect of normalizing blood sugar levels. 1-3Ĭhromium is now generally recognized to play an important role in glucose and lipid metabolism. Patients recovered after at least 150 micrograms (mcg) of trivalent chromium was added to the formula. Chromium deficiency was eventually recognized as the cause of the symptoms. Reports began to appear in the medical literature describing patients who developed glucose-handling disorders and abnormalities of the motor and sensory nerves after prolonged nose-tube feedings with a liquid nutrient formula that was believed to supply all necessary nutrients. Later, a similar effect was documented in humans. Researchers then switched the animals’ feed to brewer’s yeast-a rich, natural source of chromium-and the rats’ health promptly returned to normal. The unfortunate rodents quickly developed glucose intolerance, a condition that often precedes the development of type II diabetes in humans. In the mid-twentieth century, scientists put laboratory rats on a diet devoid of chromium. doi:10.Chromium, the metallic element once believed to be toxic, is in fact essential to health.
