You might wonder how a pill works if you lack intrinsic factor: at very high oral doses, a small amount of B12 can be absorbed directly through the gut wall via passive diffusion, bypassing the need for intrinsic factor entirely [1] [3]

B-complex vitamins serve as coenzymes or precursors in numerous biochemical reactions, and together they work synergistically to support metabolism, neurological function, and cellular energy production
IM Shots can be more effective than ingesting vitamins and supplements orally since shots bypass the first-pass metabolism which can make the oral supplement less effective
A clinician can recommend the right form (oral, sublingual, or injection), dosing schedule, and follow-up testing to ensure treatment is safe and effective
