B12 treatment guidelines

Hello all,

I am new to all this and I was looking for some help, I have been denied treatment for a possible b12 deficiency.

My b12 levels are 215 range 180-2000

I am in the process of writing a complaint letter to the consultant that my gp referred me too.

I was looking for help with the guidelines for treatment where results are in low normal range and you have symptoms.

Please can you help point me in right direction.

Many thanks

BMJ B12 article emphasises that people who are symptomatic for B12 deficiency should be treated even if B12 is within range.


Point 5 in next link is about being symptomatic with an in range B12 result.

Have you looked at the summary of B12 documents in the third pinned post (last link in list)? I found it very useful.
