Vitamin B12 deficiency is now more prevalent than ever. It is a common cause of megaloblastic anemia, neuropsychiatric disorders, and other clinical manifestations. Screening is required in patients with single or multiple risk factors. Measurement of serum methylmalonic acid can be used to confirm deficiency in asymptomatic high-risk patients with low-normal levels of vitamin B12. Oral administration of high-dose vitamin B12 as well as intramuscular administration are effective as corrective therapy. This review briefs about the pharmacokinetics and pharmacodynamics of Vitamin B12, risk factors associated with its deficiency, screening methods and treatment options.
