B12

Hi . I have fibro. I also had bariatric surgery nearly 2 years ago. They keep an eye on my b12 levels as it is a side effect of the surgery. My levels started at over 500 but have come down to 150. My doc will not give me any booster cos she said I am still within normal levels. I was under the impression that if u are below 200 then u should have booster injections but she said it is below 140. Do u know which is correct

  • I don't know the answer to this however you are entitled to seek a second opinion, I think you should.

  • Hi juliekp

    I have taken this extract from livestrong and it may answer your question for you:

    Normal Levels

    Your doctor can measure your vitamin B12 levels through a blood test. Because of the general safety of the vitamin, upper limits for normal intake do not exist. If your blood values for the vitamin fall below a range of 170 to 250 picograms per milliliter, you may develop a B12 deficiency. However, blood tests do not necessarily accurately reveal the presence of a deficiency -- testing levels of a substance called methylmalonic acid may give a better picture of potential B12-related problems.

    Here is the link to the rest of the information:

    I want to wish you all the best of luck with this issue.

    All my hopes and dreams for you
