The AAFPs evidence-based clinical review states directly: Oral administration of high-dose vitamin B12 (1 to 2 mg daily) is as effective as intramuscular administration for correcting anemia and neurologic symptoms in patients with B12 deficiency (Langan RC, Goodbred AJ, American Family Physician, 2017)
