Question: Who would benefit from a B12 shot? Who should not get one?
Answer: Anyone with low vitamin B12 levels may benefit from B12 injections. You should not get a B12 injection if you are allergic to cyanocobalamin (vitamin B12). Ask your doctor if you are pregnant, or plan to become pregnant, or if you are breastfeeding before having a B12 shot.
Question: How long do the effects of a B12 shot last? How often should you get them?
Answer: It depends on your vitamin B12 level and how fast your body absorbs vitamin B12. Typically B12 injections are administered on a weekly basis, but talk to your doctor to see how often is right for you.
Question: What are the negative side effects of a B12 injection?
Answer: Most people have no or very minimal side effects from B12 injections, but some adverse reactions may be dizziness, headache, upset stomach, nervousness, or diarrhea.
Question: How is a B12 shot different than getting B12 through dietary intake?
Answer: B12 shots are the preferred method of administration, since dietary intake (oral route) has variable absorption rates.
