This is a bit of a stupid question, but I can’t seem to get it straight in my mind. I currently have low B12. Whilst I await results from a MMA and homocysteine test, I’ve been looking at supplements.
Now I can order sublingual tablets for B12, but I wondered how do you know if you have a problem absorbing b12 through the normal channels? I know that body doesn’t need much B12 daily, so if you are low then either you aren’t getting enough in your diet, or there is a problem. But how do you know that simply taking an increase in B12 as a normal tablet won’t solve the problem? You could take them and see if there was any improvement, but apart from that and having another blood test, how would you know? For reference my anti-intrinsic factor came back negative.
Like I said a stupid question, but something I couldn’t answer myself?
PS. The tagging system is awful, how many times have I mentioned b12 (there's another!) and that's not even one of the tags, and you can't edit them either....
