injectable vs sublingual b12 Oral vs. Intramuscular Vitamin in Vitamin B12 Deficiency • The Blood Project Compounded Cyanocobalamin (Vitamin B12) Injection
Description
I dont need the needles, however

Screening for vitamin B12 deficiency is done for patients with one or more risk factors, such as gastric or small intestine resections, and inflammatory bowel disease

Surgeries that affect the stomach where intrinsic factor is made, or the ileum (the last portion of the small intestine) where vitamin B12 is absorbed, can increase the risk of a deficiency
