WebChromium is an essential mineral that the body needs in trace amounts. It is naturally present in a wide variety of foods, though only in small amounts, and is also available as a supplement. Chromium enhances the action of the hormone insulin. [1) It is also involved in the breakdown and absorption of carbohydrate, proteins, and fats.
