I have just returned from my GP review following recent blood tests for anemia. She wants me to start a course of injections with loading then 3 monthly shots. I produced my pot of 5000 microgram B12 tablets by Jarrow but she shook her head sadly and said no, not to take them as they could skew results and absolutely would not work. I don't do well with injections of any kind - they usually kick off an inflammatory response so I try to avoid them where possible. Is she right?
