Hello
Welcome To Ask A Doctor Service
I have gone through your question, I understand your concern.
Actually sometimes oral tablets take much longer time to show their effect.
So if even after one month of treatment you are not feeling better, then you should start injection vitamin B12 intramuscular daily.
It will lead to to faster relief of your symptoms.
I hope your query is clear now.
Thanks and regards

I have gone through your question, I understand your concern.
Actually anything below 200 is low.
You cannot say that this is borderline.
Borderline would be around 200.
But your level is quite below 200, so this is definitely low and not borderline.
I hope your query is clear now.
Thanks and regards
