B12

Hi all I went to the doc for a b12 test as I have pins and needles and burning n my feet not sure what is causing this but my test came back fine. I have asked for my results but as yet not got them. I was wondering if anyone else suffered from this I am a type 2 diabetic as well but they said nothing to do with this. It is keeping me awake at night.i have started taking 5000 of b12 can't do any harm.

  • Did you start taking the B12 before your test ? If so then the results will be skewed. Are you taking the Jarrow B12 ? - if so ensure it stays under the tongue until dissolved. You cannot overdose on B12 as it is water soluble and so any excess is excreted. You also need to take a GOOD B Complex - to keep all the B's in balance.

    Hope you get your results soon.... being fine is not an adequate response. Anything UNDER 500 will cause neurological conditions.

  • No did not start b12 till after the test.

  • Hello chris48,

    Your doctor should know that neuropathy is one of the long-term complications of diabetes as a result of high blood glucose levels damaging the small blood vessels which supply the nerves. This prevents essential nutrients reaching the nerves which then get damaged or disappear.

    A B12 deficiency can be confirmed with a blood test but the blood serum measures ALL the B12 in your blood and there is only a small proportion that is "active" and works within the cells. However, there is a test measuring only the active B12 in your blood, detailed in following link.

    The test is also available on the national health at St Thomas' Hospital in London and apparently you can send a sample with a GP's letter but I used Blue Horizons private testing and it cost about £70.00. I have neurological problems in my extremities too but my active B12 is high so this was not my answer.

    Neither my GP and haematologist had not heard of this test so if you plan to approach your doctor, it would be best to go armed with info on it.

    Hope you find your answer soon,

  • Thank you might have to do a diy test. It is just so uncomfortable when your feet like this.

  • Nhs also told me my tests were normal when I had pernicious anaemia.
