What is pernicious anemia and why do you need B12 injections if you suffer from it
Vitamin B12 requires an intrinsic factor-mediated active transport for absorption, therefore, lack of or inhibition of intrinsic factor results in pernicious anemia
Vitamin B12 injections are significantly more expensive than oral supplements when accounting for the full cost of treatment including office visits, injection fees, and ongoing maintenance appointments
Low vitamin B12 levels cause a reduction in red blood cell formation and prevent them from developing properly
