What is chromium?
Chromium is an essential mineral that the human body needs in trace amounts. Chromium enhances the action of insulin, the hormone that helps blood sugar enter cells so it can be used for energy. It is also involved in the breakdown and absorption of carbohydrate, proteins, and fats. Vitamin B3 (niacin) and vitamin C help to improve the absorption of chromium.
Chromium is naturally present in a wide variety of foods, though only in small amounts, and is also available as a supplement. Chromium exists in two main forms: trivalent chromium (III) and hexavalent chromium (VI). Trivalent chromium is found in food and supplements and is not toxic. Hexavalent chromium is found with industrial pollution and is toxic and carcinogenic when inhaled.
