What is cobalt?

Cobalt, element 27, is a transition metal, and it is in Group 9 on the periodic table.

Cobalt is critical to industry. It is used in making a number of different metal alloys, as a catalyst, and is used in compounds to manufacture coloring agents.

It is a tough, lustrous silver-white magnetic metallic element that is related to and occurs with iron and nickel and is used especially in alloys.

In nutrition, cobalt is a trace mineral that forms part of the structure of vitamin B12. The total amount of cobalt in your body is 1.1 mg. It is readily absorbed from your small intestine, and your liver stores most of your body's cobalt.

Cobalt is essential to humans as well as to animals. It is the main constituent of cobalamin, also known as vitamin B12, that is basically cobalt's biological reservoir. The activity and function of cobalt is essentially the same as vitamin B12. Cobalt also assists in regulating enzymes that break down proteins, including casein, phosvitin, and other phosphoproteins. Along with nickel and manganese, cobalt can be a good alternative for zinc in some enzymes.
