How does vitamin B12 give you energy?

205 views

I’m taking B12 shots in conjunction with some other medication and I find that I’m not tired all day. I’m not hyper, by any means, but I feel really evened out and alert the whole day. How does this happen? Is it something in my brain? Is it something in my body?

That’s probably how you’d feel normally.

It’s not that B12 is making you feel more energetic *per se*, but rather that your *B12 deficiency* makes you feel *less* energetic, and the shots bring you back up to normal.
