I'm feeling a little concerned about this. My mam told me that she was tested ages ago and it came out as 251. Recently someone told her that anything under 250 would requite treatment (injections). In the US the lower limit is 400 and in Japan it is even higher at 500-600. We have the highest rate of dementia in the UK, probably due to low B12!
I decided to call my doctors as I had a test a few months back. Mine is 271.... so, also quite low. I've bought some pills but I'm not sure if they're as effective as injections (not that I fancy getting those).
Does anyone know anything about this?
