Vitamin B12 is essential for DNA synthesis and for cellular energy production. Vitamin B12 is also known as cobalamin. There are several forms of cobalamin including cyano-, methyl-, deoxyadenosyl- and hydroxy-cobalamin. The cyano form, which is used in supplements, is found in trace amounts in food. It is assumed that 50% of dietary vitamin B12 is absorbed.

Deficiency of Vitamin B12 is usually caused by the malabsorption of vitamin B12. Dietary deficiency is common in the elderly, vegans or ovo-lacto vegetarians, or with poor diets. Causes can also relate to inadequate Intrinsic Factor, (IF), production, atrophic gastritis, interference with the uptake of vitamin B12 in the ileum due to disease, resection or gastric by-pass if this effects the ileum or interference by bacterial overgrowth, drug-nutrient interactions, and some less common genetic defects. Diseases of the ileum such as Crohn’s Disease or other chronic bowel inflammatory conditions also cause malabsorption of vitamin B12

Pernicious anemia leads to Vitamin B12 deficiency due to the loss of Intrinsic Factor. This is the end stage of an auto-immune gastritis. If untreated, megaloblastic anemia and neurological complications develop. Pernicious anemia is treated with Vitamin B12 injections, or large doses of oral vitamin B12.

Some medications are thought to interfere with the absorption or metabolism of vitamin B12. These include proton pump inhibitor (PPI) medications, metformin, nitrous oxide anesthesia, some epileptic medications, and colchicine.
