I recently had a well-being check at my GP and had the usual bloods taken.
My results were fairly normal but I noticed my B12 levels were quite low at 200 ( the bottom range is 100).
I have a good diet which includes all the foods recommended for boosting B12 levels so I thought maybe I have a problem absorbing B12.
I have just started taking sublingual B12 supplements and plan to ask for a further test in 3 months time.
If my results improve would this prove I may have a problem with how my gut absorbs B12. Would injections help?
