Vitamin B12, also known as cobalamin, is a water-soluble vitamin involved in metabolism.[2][3] It is one of eight B vitamins. It is a cofactor in DNA synthesis, in both fatty acid and amino acid metabolism.[4] It is important in the normal functioning of the nervous system via its role in the synthesis of myelin,[3][5] and in the maturation of red blood cells in the bone marrow.[6]
The most common cause of vitamin B12 deficiency in developed countries is impaired absorption due to a loss of gastric intrinsic factor (IF) which must be bound to a food-source of B12 in order for absorption to occur.[7] A second major cause is age-related decline in stomach acid production (achlorhydria), because acid exposure frees protein-bound vitamin.[8] For the same reason, people on long-term antacid therapy, using proton-pump inhibitors, H2 blockers or other antacids are at increased risk.[9] Deficiency may be characterized by limb neuropathy or a blood disorder called pernicious anemia, a type of megaloblastic anemia. Folate levels in the individual may affect the course of pathological changes and symptomatology of vitamin B12 deficiency.
