Vitamin B12 is absorbed in the terminal ileum (the last part of the small intestine). The process of absorption occurs by dietary B12 becoming bound to R-protein in the saliva, the B12 is then cleaved from R-protein by the acidic conditions in the stomach. Gastric parietal cells secrete a substance called Intrinsic Factor, which binds the B12. In the terminal ileum there are receptors for intrinsic factor and both are absorbed. Problems with this absorption can occur if the body makes auto-antibodies to intrinsic factor, this means there is problems with B12 absorption and a condition called pernicious anaemia can result. The answer you wanted is the first line, but I hope the extra information is either helpful or of interest. Pete (medical student in the UK)
