Hi All,

After testing below range for vitamin B12 I have just received the results of the intrinsic factor blood test and it states intrinsic factor ABS negative. Does this mean I can supplement with b12 now? And folate? At what dose? I know I’m low in b12 but the only symptom I have is hairloss! I would rather not have the injections as I’ve heard a very common side effect is acne. I’m already down enough about the hairloss without adding acne into the mix! I already supplement with iron tablets so my ferritin level is over 100 and I’m on loading doses of vitamin d too.

Thank you!

I would ask your question over on the PA forum. From what I have read the intrinsic factor test can come back with a false negative. See what they say, as a dedicated B12 forum I think they're in the best position to give you an answer.
