What is B12?

B12 is an important water-soluble vitamin that many people have a deficiency in. Approximately 85% of the population actually has a deficiency in this vitamin. B12 plays a very important role in our brain's functioning and helps produce DNA as well as red blood cells. B12 contains the mineral cobalt. This is a vitamin that is stored in the liver, so a deficiency can take a long time to appear. B12 deficiencies can lead to neurological issues and anaemia, so B12 injections are the best way to get B12 into the body.
