Vitamin B12, referred to as VB12, is also called cobalamin. It is one of the B vitamins and a class of cobalt-containing corrinoid complex organic compounds. It is the largest and most complex vitamin molecule discovered so far, and it is also the only vitamin containing metal ions. Its crystals are red, so it is also called red vitamin. Plants do not contain VB12 and cannot produce VB12. The liver is the best chemical source of VB12, followed by milk, meat, eggs, fish, etc. VB12 is a necessary coenzyme in the synthesis of ribonucleic acid and deoxyribonucleic acid. VB12 deficiency in the body can cause pathological changes in the nervous system such as peripheral nerves and central encephalopathy.
