Wherever we are in the world, we are all in the same boat…

There are many problems associated with diagnosis and treatment of B12 deficiency and many of them boil down to a lack of education of health professionals. They have all been done a disservice.

This is a worldwide problem.

Serum B12 blood results
I help people to access the treatment they need and always urge people to get a copy of their current and historical results. In some cases they have been found to be below range, but the result has been ignored whilst the patient has continued to deteriorate. Remember you are legally entitled to your results.

Our GP’s may be unaware of the limitations of the serum B12 blood test, that it can miss seriously deficient patients and that this can lead to a within range result being batch filed and labelled as ‘normal’.

Lack of education of this common condition means that our GP’s don’t necessarily understand that they cannot wholly rely on the blood results. The clinical picture is of utmost importance and if the patient is symptomatic it’s vital they access correct treatment for B12 deficiency.

It is important to note that the Active B12 test (holoTC/ Holotranscobalamin) is not gold standard either, remember that the clinical picture is key.

Treatment with tablets
Too many GP’s in the UK (and in other countries) try and treat B12 deficiency with B12 tablets and if the patient includes animal products in their diet, like the one the result belongs to below, then their deficiency is not caused by dietary lack and injections are essential. If you cannot absorb B12 from food then a tablet taking the same route won’t work either.

NICE Guidance states:

  • Not thought to be diet related — administer hydroxocobalamin 1 mg intramuscularly every 2–3 months for life.
  • Thought to be diet related — advise people either to take oral cyanocobalamin tablets 50–150 micrograms daily between meals, or have a twice-yearly hydroxocobalamin 1 mg injection.

The above result at 144 ng/L is below range and is definitely showing B12 deficiency, the patient has many neurological symptoms and as I have said, includes animal products in their diet. Unfortunately this GP (and others in the Practice) believes that 50mcg cyanocobalamin tablets are the best way to treat this patient.

In reviewing these results, the GP added their own note stating:

“B12 low, script for cyanocobalamin and repeat 2 months”.

The second sentence originates from the lab and states:

“Note low B12, deficiency possible, treat if clinically appropriate otherwise repeat after 2 to 4 months and review.”

The issue with the lab note is the term: ‘deficiency possible’ –  surely this should read ‘definite B12 deficiency’?

All labs are different, all assay kits are different and all reference ranges are different. This lab below has a low reference of 150ng/L and in my area it is 220 ng/L, in East Lancashire it’s 110 ng/L. There is no across the board standard which help either the doctor or the patient.

The patient that these results belong to continued to feel unwell, had absolutely no abatement in symptoms but due to the supplementation of the 50mcg tablets there was a small raise in the serum B12 level to 161ng/nl. This confirmed to the GP that the patient could absorb B12 and they were instructed to continue with the tablets. In fact, the patient was told that they could ‘definitely absorb B12’.


This would not have happened had the GP been properly educated about B12 deficiency.

Waste of time, money and NHS resources
This patient went back to see the GP repeatedly due to feeling no improvement and each time their B12 serum level was tested. Each time they were told that they should continue with the tablets for another 2 months. How frustrating is it to even read this, never mind live this?

My recent involvement in this case provided the information the GP needed to treat the patient as per NICE Guidance and how cyanocobalamin should only be used for patients with B12 deficiency of dietary origin.
However, I was told that the Practice were following another protocol and that they felt the patient hadn’t taken the tablets religiously and this was the reason for no improvement.


After nearly a year of zero improvement in symptoms I think most of us would be hard pushed to take a tablet which was proving to be a pointless treatment.

A tricky but simple case
Thankfully common sense has now prevailed and the Practice has decided to give the patient the correct treatment of B12 injections. It took many phone calls and emails for this to be actioned. The people I asked to speak to were often ‘in a meeting’ but I don’t give up.

It should not be that any patient is left for 11 months without correct treatment for this common and easy to treat deficiency.

This practice were very annoyed that I was advocating for the patient, they said that there was no need for “3rd party involvement” however in this case and in fact all that I get involved in, there absolutely was a need.

Until education on B12 deficiency is the norm, it will continue to be that outside agencies are needed to help health professionals of all disciplines to understand the seriousness of this condition and what correct treatment should be.

We are all the same
Many of us know how difficult it can be to challenge a doctor, especially those that have their heels so firmly dug into the ground.

Fortunately I learnt long ago that it can be unsafe not to challenge doctors, that they are no different to the rest of us, that they are not infallible, and they can correct their mistakes if they choose to – if the infrastructure allows them to.

I am thankful to all those health professionals who appreciate being furnished with the correct information about B12 deficiency and who regularly use my site.

  1. I am sad to read so many B12 deficiency sufferers still only get three monthly injections. As Elizabeth Kubler Ross once said ‘pain is what the patient says it is’ – not what health professionals etc. think it should be. Luckily I have a GP who listens to her patients and provides me with B12 injections weekly which I self administer. I have never looked back. It took me a while to admit some of my symptoms were due to B12 deficiency having suffered all my life with chest/lung problems. Mostly GP surgeries are more concerned about being inundated with so many injections if given weekly but patients can be taught to self administer or even pharmacists or relatives be enlisted to help out. So anyone out there who finds B12 injections work for them but need more than three monthly injections the tackle your GPs again and again not everyone is in a position to purchase the injections and this involves sourcing abroad as we can’t purchase them over the counter in Britain. The B12 deficiency.info site has been running for many years now and contains well researched facts and information with plenty of advice and help for those who need it. It is up to us to be responsible for our own health and GPs should be aware that not all patients are the same ‘one cap does not fit all’ so take the bull by the horns and talk to your doctor if mt doctor can do it so can yours. I know from experience how difficult some people find it to be in conflict with GPs but there is help on the B12 deficiency.info site so don’t be afraid to use it. If you have been diagnosed with B12 deficiency you are well on your way if three monthly injections are not sufficient then fight for more as is your right.

  2. If I was this patient I would change my doctor pronto! As I understand the UK system you have to register with a medical practice to be covered by the NHS. How difficult is it to change doctors if you are dissatisfied with the one you’ve got now? Obviously if you live in a rural area you may be somewhat limited for choice, although my observation of the UK is that other than the Scottish Highlands or the Hebrides most “rural” locations are never far from a reasonably large town. Not like here in Australia where the nearest doctor may be a 100-mile round trip away.

  3. Hi Tracy this is not an isolated case it happens all over the UK and it becoming standard practice, being cited now as first line treatment in many local guidelines (I’m a practice nurse)

    National/BSH guidelines are being ignored

    • Dear Claire
      Thank you for your comment.
      I agree, too many people contact me about this.
      Are you able to help your GP’s to understand what they should be doing?
      Do you have your own Practice Protocol? Does that advocate tablets too?

      Best wishes
