Most likely.....: Folic acid, or possibly B12 in the setting of deficient but not completely absent intrinsic factor synthesis. The eqivalent of pernicious anemia can be caused by inadequate B12 intake, inadequate intrinsic factor production by parietal cells (autoimmune destruction, atrophic gastritis, etc.) or inadequate absorption at the terminal ileum (also for many reasons). Some other rare reasons as well.
