Hi Mrs. D - I stopped all supplements 3 weeks before getting my B12 levels tested. Before that I was not using the B12 supplement very regularly. I had it in a liquid (mouth spray) form and would forget to use it most of the time. All my other supplements are in pill form. I was also taking a B6 and Biotin supplement.

I have no idea why my B12 levels were high? Could it be from eating certain foods? Could it be that my body is not absorbing it properly so it is showing high levels in my blood? Could meds I am taking affect it? I have been on a long term dose of Lamisil for chronic yeast.

Not sure. All I know is that I was not using the B12 supplement spray even half the time because I would forget to do the spray.

Thank you.
