What is B12 used for?
Vitamin B12 functions as a cofactor for two enzymes, methionine synthase and L-methylmalonyl-CoA mutase [ 1-3, 5 ] . Methionine synthase catalyzes the conversion of homocysteine to the essential amino acid methionine [ 1, 2 ].
How is vitamin B12 released?
Vitamin B12 is bound to protein in food and must be released before it is absorbed [ 5 ]. The process starts in the mouth when food is mixed with saliva. The freed vitamin B12 then binds with haptocorrin, a cobalamin-binding protein in the saliva. More vitamin B12 is released from its food matrix by the activity of hydrochloric acid and gastric protease in the stomach, where it then binds to haptocorrin [ 1 ]. In the duodenum, digestive enzymes free the vitamin B12 from haptocorrin, and this freed vitamin B12 combines with intrinsic factor, a transport and delivery binding protein secreted by the stomach’s parietal cells. The resulting complex is absorbed in the distal ileum by receptor-mediated endocytosis [ 1, 5 ]. If vitamin B12 is added to fortified foods and dietary supplements, it is already in free form and therefore does not require the separation step.
How much B12 is in a multivitamin?

No evidence indicates that absorption rates of vitamin B12 in supplements vary by form of the vitamin.
How to determine vitamin B12 levels?
Vitamin B12 status is typically assessed by measurements of serum or plasma vitamin B12 levels . The cutoff between normal vitamin B12 levels and deficiency varies by method and laboratory, but most laboratories define subnormal serum or plasma values as those lower than 200 or 250 pg/mL (148 or 185 pmol/L) [ 2 ]. Levels of serum methylmalonic acid (MMA), a vitamin B12-associated metabolite, are the most sensitive markers of vitamin B12 status, and an MMA level greater than 0.271 micromol/L suggests vitamin B12 deficiency [ 6-8 ]. However, MMA levels also rise with renal insufficiency and tend to be higher in older adults [ 6, 9, 10 ]. Another marker is total plasma homocysteine levels, which rise quickly as vitamin B12 status declines; a serum homocysteine level higher than 15 micromol/L, for example, suggests vitamin B12 deficiency [ 11 ]. However, this indicator has poor specificity because it is influenced by other factors, such as low folate levels and, especially, by declines in kidney function [ 6 ]. Experts suggest that if a patient’s serum vitamin B12 level is less than 150 pg/ml (111 pmol/L), the patient’s serum MMA levels should be checked to confirm a diagnosis of vitamin B12 deficiency [ 7, 9 ].
