No function of cobalt in human nutrition other than as an integral part of vitamin B12. The vitamin plays important role in the body, especially in cells where active division is taking place, such as in blood forming tissues of bone marrow.

In addition who drink large amounts of beer, containing 1-2 ppm of cobalt salts added as a foam stabilizer, in many cases polycythemia, pericardial effusion, thyroid epithelia hyperplasia and neurological abnormalities.
