The vitamin is a cofactor for methionine synthase, which catalyzes the conversion of homocysteine to methionine—required for the formation of S-adenosylmethionine, a universal methyl donor for almost substrates, including DNA, RNA, hormones, proteins, and lipids.

Methionine also is needed for the synthesis of myelin, a coating of the nerve pathways. Vitamin B12 is a cofactor for L-methylmalonyl-CoA mutase, which converts L-methylmalonyl-CoA to succinyl-CoA in the degradation of propionate, an essential biochemical reaction in fat and protein metabolism. Succinyl-CoA also is required for hemoglobin synthesis.

B12 digestion and absorption requires the adequate synthesis of hydrochloric acid, proteases enzymes that break down proteins and peptides , and intrinsic factor a glycoprotein secreted in the stomach.

The vitamin is released from dietary proteins by pepsin an enzyme secreted in the stomach and activated by hydrochloric acid. B12 binds with proteins secreted in the saliva, and in the small intestine pancreatic proteases digest the proteins, liberating the B12 to form a complex with intrinsic factor. Vitamin B12 can then be absorbed into the bloodstream via endocytosis in the distal ileum, or by passive diffusion in the absence of intrinsic factor.

Pernicious anemia an autoimmune disease affects the gastric mucosa, leading to destruction of parietal cells and failure to produce intrinsic factor, resulting in vitamin B12 malabsorption and eventually deficiency.

Older adults, who often suffer from decreased hydrochloric acid in the stomach, and individuals with gastrointestinal GI disorders may have lower absorption of B Vitamin B12 deficiency may be characterized by megaloblastic anemia, fatigue, weakness, constipation, loss of appetite, soreness of the mouth or tongue, and weight loss; and neurological conditions, such as numbness and tingling of the hands and feet, difficulty with balance, depression, confusion, dementia, and poor memory.

The neurological symptoms can occur without the presence of anemia, thus early detection is important to avoid irreversible damage. Deficiency is also commonly misdiagnosed, because symptoms can mimic other conditions.

Large intake of folic acid—common in vegan diets—can mask the damaging effects of B12 deficiency by correcting anemia without addressing the neurological damage that occurs. High folic acid may even exacerbate anemia and cognitive symptoms. Sources of Vitamin B12 Vitamin B12 is only synthesized by microorganisms.

Thus, it isn't found in foods of plant origin. Natural animal food sources of vitamin B12 which come from the animal's intestines or from their diet include fish, meat, poultry, eggs, milk, and milk products. Though some bacteria in the small intestines produce B12, it isn't enough to maintain adequate status in humans. Plants have no B12 requirement; therefore, they don't have any active mechanisms to make or store it.

When you find B12 in plants, it's due to contamination and thus isn't a reliable source. Many seaweeds have B12 analogues through their symbiotic relationship with cobalamin-producing bacteria; however, the evidence isn't clear that this form is active B12 in humans. And fermented foods, such as tempeh, aren't fermented through Bproducing bacteria, thus they aren't a source of B Rumors about bacteria on the surface of organic produce producing B12 haven't been verified.
