B12 or not B12??


Hi all, I’ve been feeling unwell (dizzy, tired, confused, weak) for over 18 months, B12 was 392 at the “beginning”, so seemed ok.

When I feel unwell my blood pressure is low (78/58 today).

If I take lots of B12 I seem to improve, but get acne, and I’m not sure I’m even doing the right thing, seeing I’ve not been diagnosed with low B12.

Any advice please?

If you haven't supplemented then try repeating the serum B12 test - if there has been a significant drop - more than 20% then that is good evidence that you have an absorption problem.

Otherwise you could have a genetic problem with metabolising B12 - though they are quite rare - and may need higher levels of B12 to ensure that your cells get enough to run all the processes they need to run.

Not sure about the blood pressure - would suggest seeing your GP about that one - certainly looks on the low side.
