As per the questions,

Vitamin B 12 is basically a water-soluble vitamin naturally present in fish, dairy products and so on. The most important mineral present in Vitamin B 12 is Cobalt, the chemical symbol is Co. That's why it is also called Cobalamins. It exists in several different forms and very important for red blood cell formation and DNA synthesis.
