Methyl-B 12 is absorbed by an intestinal mechanism using intrinsic factor and by a diffusion process in which approximately 1% of the oral dose is absorbed. The human physiology of vitamin B 12 is complex, and therefore is prone to mishaps leading to vitamin B12 deficiency.ecause intrinsic factor is crucial for the normal absorption of B 12, its lack in pernicious anemia causes a vitamin B12 deficiency. Many other subtler kinds of vitamin B 12 deficiency and their biochemical effects have since been elucidated.
