All three substances are needed for the production of red blood cells. Vitamin B12 and folic acid are necessary for DNA synthesis in the rapidly dividing cells that produce RBCs, while iron is a critical component of hemoglobin, the protein that carries oxygen in RBCs. Without any of these substances, the production of red blood cells can be impaired, leading to anemia.
