Hi again, 10 weeks ago after 5 injections my B12 levels were report to have gone from 113 to 'over 2000' it took a few weeks to begin to feel better but over time my energy levels increased. My GP said I would not need anymore B12 for a few years as my IF/parietal cells was negative and it was probably diet related. I have worked hard to increase dietary food that contains B12 even though I dislike many of the things I am eating.
Last week I began to feel very unwell with extreme fatigue muscle aches pins and needles. My GP agreed to repeat B12 after I told him I had been supplementing and also taking Vit D. The result has come back to 413 which is within normal limits but dropped dramatically, the lab have commented that there will be enough B12 for 2 years but isn't this drop pretty dramatic, I do not know where to go from here? Any advice would be helpful please
