Kiskila croppedQuestion: Dr. Kiskila, what exactly is a B12 injection and what does it do?

Answer: A B12 injection is a vitamin that helps treat anemia, helps to prevent or treat low vitamin B12 levels, helps metabolize fat and carbohydrates, and synthesizes protein.

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.
