This simulator demonstrates the distinct absorption pathways of vitamin B12 and folate, showing how blocking intrinsic factor, parietal cells, or the terminal ileum halts B12 uptake while folate absorption continues largely unaffected.
Toggle conditions such as gastric surgery, pernicious anemia, or terminal ileum disease to see how each disrupts B12 absorption specifically, then compare the resulting effects on red blood cell size, anemia severity, and neurological risk.
Interactive toggles let users simulate gastric surgery, pernicious anemia, and intestinal disease to observe their distinct effects on B12 versus folate absorption and downstream blood and neurological outcomes.
Did you know that the body can store several years' worth of vitamin B12 in the liver, which is why B12 deficiency from absorption failure often takes years to produce noticeable symptoms, unlike folate deficiency, which can develop within weeks?
