Vitamin B12 and folic acid deficiencies present with symptoms like anemia and birth defects, but the underlying mechanism remains unclear. We show that B12 and FA antagonize aryl hydrocarbon receptor, which has been implicated in anemia and birth defects. We found that treatments with B12/FA rescued mice from AhR agonist-mediated anemia, fatty livers, and cleft palates.
