Cobalt is a trace lement found widely in the environment. Cobalt is a hard ferromagnetic silver-white element.
It is required in the manufacture of red blood cells and in preventing anemia.
Food Sources of Cobalt
Good food sources of cobalt include fish, nuts, green leafy vegetables (such as broccoli and spinach), and cereals (such as oats).
Benefits and Functions of Cobalt
Cobalt in small amounts is essential to many living organisms, including humans. Having 0.13 to 0.30 parts per million of cobalt in soils markedly improves the health of grazing animals. Cobalt is a central component of the vitamin cobalamin, or vitamin B-1.
Adults need approximately 0.0015 mg (1.5 micrograms) of vitamin B 12 a day. Having 1.4 mg or less a day of cobalt supplements is unlikely to cause any harm.
Overdosage Signs of Cobalt
Having high amounts of cobalt for long periods of time could affect the heart and might decrease fertility in men. An excessively high intake of cobalt may damage the heart muscles, and may cause an over-production of red blood cells or damage to the thyroid gland.
