Cobalt - Information and Sources


Cobalt is a trace mineral but is only essential for humans as part of the structure of vitamin B12 and requirements of both micronutrients are closely linked. The amount of cobalt we consume is dependant on vitamin B12 intake as well as the soil and conditions where crops are grown and animals are reared.

Cobalt is widespread in our diet. Good food sources of cobalt include:

  • Fish
  • Red meat
  • Liver
  • Oysters
  • Milk
  • Nuts
  • Green leafy vegetables
  • Wholegrain cereals
  • Oats
