Chromium 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.
Uses. Chromium is alloyed (that is, mixed) with steel to make it corrosion-resistant or harder. An example is its use in the production of stainless steel, a bright, shiny steel that is strong and resistant to oxidation (rust). Stainless steel production consumes most of the chromium produced annually. ... The MEC Mineral Baby details the ...
