Vitamin B12, also known as cobalamin, is a complex organic compound that belongs to the B vitamins. It contains trivalent cobalt in a porphyrin Corrin plane at the center of the ring, making it the largest and most complex vitamin molecule. Vitamin B12 is the only vitamin that contains a metal ion, giving it a red crystal appearance.

Plant sources do not contain Vitamin B12, so it cannot be naturally produced by plants. The liver is the best source of Vitamin B12, followed by milk, meat, eggs, and fish. Vitamin B12 plays an essential role as a coenzyme in the synthesis of RNA and DNA. A deficiency of Vitamin B12 can lead to pathological changes in the nervous system, affecting both the peripheral nerves and the central nervous system.
