my b12 was tested in the summer and it came back as 113 so I had loading injections my parietal cell and intrinsic factor antibodies were negative. could it be that my thyroid is the culprit for the low b12 as I have hashimotos and I have just read that this can make your b12 low. is that right? If so are there any tests I should have to find out or any action I can take to make sure it does not happen?
Thank's for any help
