I was hoping someone could help me with the frequency of my vitamin b12 shots. My levels were very low in October of last year 223. After a lot of convincing my neurologist finally put me on shots in December. I took the shots in December and January. Prior, I took oral supplements. I skipped February because my numbers were way up. My b12 went way up to 1309 by January 15th. I just had it tested on Friday and my level is 935. I am a vegan.

My question is how quickly does your body deplete the vitamin? Should I take the next shot in the middle of March or beginning of April? My doctor recommended every other month. Is that often enough?
