    Re: DO you have B12 injections?

    If you have already been supplementing with B12, I'm afraid this will skew your results and give you a higher reading than you would normally have, even if you do stop the doses beforehand. Truly, the body does use only about 2mcg per day, but it needs a great deal more than that "in store". The ranges quoted as lab reference ranges are there to help the doctor and no way are they "optimal" for the patient, as with the thyroid ranges.

    Most people aim to get their levels up to, or above, 500, but even so this is no indication that they will be symptom free (The lab ranges in Japan start at 500, but the average range in UK, Europe and USA is something like 200-1000.) If your levels are less than 300 you should consider supplementing, even if your doctor says "normal", it is only a vitamin and cannot harm.

    Many people have low levels of B12 because they simply cannot absorb the vitamin properly from their food, particularly of they are Coeliac, have IBS, Chrones Disease or other malabsorption problems, or are vegan or vegetarian, the main source being red meat and fish. My levels, with injections and sublinguals are over
    1400, but I still have symptoms although minor.

    SiD, no I do not feel any different after I have the injections, I have often wondered about this, as most people do feel better within a few days (I am beginning to wonder if the B12 is pooling in the blood but not available to the cells, like in the T4-T3 conversion). I was diagnosed with PA not on B12 blood levels but on Parietal Cell Antibodies and a Schilling Test, eight years ago.

    Re: DO you have B12 injections?

    Hi

    I am on B12 injections daily - My GP doesnt agree with this but a specialist I see sends me the B12 around 15 a bottle 3 months supply. I do get my needles and sharps bins from GP though

    The B12 initially took around two weeks before I felt any effect, I felt so much better, memory and energy levels. At one point my GP asked me to come off it for a while as my bloods were >1500

    I agreed and within a month I was bedbound half the time!

    Needless to say I am back on the B12, its not all plain sailing I do have alot of bruising and now have become phobic of injecting myself, so my husband does it. On a weekend I dont have the injections so I have a little relief from the jabs.

    Bruised but mobile

    So what sort of benefits did you observed sherrie? How long were you hypothyroid and were your B12 levels were very low when you started those?

    Hi there, Sherrie

    Good to know you have been able to get injections - I am not allowed to self inject but I don't
    think I could do it anyway, so I am stuck with once every three months and have to supplement
    sublingually.

    What injections do you have, is is methycobalimin? or Hydroxycobalimin? And what were your levels
    to cause your specialist to give yuou B12?

    I hope you have had your folate and ferritin levels checked too. as if these are low they can stop the B12
    working properly.

    Re: DO you have B12 injections?

    I started doing them weekly over a month ago and I have to say I feel pretty good. I was taking 2000 mcg subligually for over a year and had my levels retested and they were actually lower than when I had my levels first tested. Mine were not too low but my NP recommends having levels from 1400-2000 and mine were around 700. It takes me a few minutes to work up the nerve to inject but I think it's worth it. I also started going to an acupuncturist but I think the B12 has a lot to do with my feeling so much better. I would recommend at least trying it and seeing how it goes.

    Re: DO you have B12 injections?

    Yes I have read on the PA Forum that doing very frequent injections can be very wearing, some people have
    to do them daily. I have a real needle phobia, but I can just about cope if I shut my eyes and dont see the
    needle coming. It would be difficult to self inject with the eyes shut though.

    Hydroxycobalimin has to be Intra Muscular (IM), but I believe the methyl injections are sub-cutaneous(SC)
    which are a bit easier to do, but need to be more frquent.

    The sublinguals don't help everyone, but it makes life easy if they do suit. With sublinguals absorption is
    about 15%, with swallowed pills it is only 1%. I forget what absorption is with injections, certainly nowhere near
    100% I believe it may be something like 45%.

    Vitamin B12 (cobalamin) is an important water-soluble vitamin. In contrast to other water-soluble vitamins it is not excreted quickly in the urine, but rather accumulates and is stored in the liver, kidney and other body tissues. As a result, a vitamin B12 deficiency may not manifest itself until after 5 or 6 years of a diet supplying inadequate amounts. Vitamin B12 may help delay Alzheimer's disease, study says The ages of the analysis group correspond to ages of those at greatest risk for developing dementia.
