A member asked:

How do i know if i need to take more b12 shots or is it dangerous?

3 doctors weighed in across 2 answers

B-12: My question is why are you taking B-12 injections? Are you anemic? If , not basic B-complex would be recommend. If, you are anemic , I would recommend you follow up with your physician and get lab test done.
