How is vitamin B12 absorbed?
The food we take can only be absorbed by the body after being split from the protein by hydrochloric acid in the stomach. To absorb B12 in the terminal ileum, the stomach’s parietal cells produce a glycoprotein referred to as the Intrinsic Factor (IF).
The free cobalamin attaches to an R protein that is removed when passing into the duodenum, allowing the cobalamin to bind to the IF and its active absorption. The B12-IF complex then moves into the small intestine where ileal receptors ingest it through phagocytosis.
