  • If don't know the reference values for A, does it say on the results? maybe you lack A in your diet? Your consultant will probably look in to it if it's clearly low.

  • The result was 0.4, unsure what it should be i have tried google but with not much luck !

  • It doesn't give on the paper? Or at least the units? (like umol, ng or something) From what I remember it's something like > 0.3 but then 0.4 would not be low, or normal is between 1 and 2.2 (umol/L) and below 0.35 is a deficiency, but difficult to say without the units, so best then to wait for the consultant.

  • This is a link to the EFSA recommendations for upper limits for vitamin and mineral supplementation - it tends to give quite a good summary of the risks and effects of various vitamins and minerals

    efsa.europa.eu/sites/defaul...

    p151 onwards.

    haven't read very far but: Vitamin A is absorbed in upper part of the small intestine - B12 in the lowest part so if there was a general problem with the whole of the small intestine ... can't say how likely that might be. Both are also stored in the liver.

  • Kaya how often are you having your b12 jabs as you seem to have a lot of health issues include fibro of Iv read correctly it maybe that your not having your injections often enough as ppl have found there fibro get better or goes away with optimal vitamins including vit d. Fibro often gets misdiagnosed when the real truth of that matter is your vitamins are still low. Vitamin d needs to be a minimum of 125nmol and b12 needs to be over a 1000 consistently for healing to occur. If you have neuro symptoms which include numbness tingling weakness memory loss confusion there are quite a few forgive me I can't remember them all then according to the medical BSCH guidelines then you should be on every other day injections til no further improvement then two monthly. There are also supporting vitamins you need to take to make your b12 work optimally. Such as folic acid as if your low in this the b12 is effectively useless. You also need a b complex to balance out all the b vitamins.

  • I was also meant to add that once in injections your levels should never be retested as the levels will always be falsely high due to the injections and will not give a true reflection on how the person is feeling
