Vitamin B12 deficiency Support Group (Charity)

The B12 Deficiency Support Group (B12d, for short) is a charity. Our aims are to:

  • Raise awareness of this condition amongst doctors and the general public, so that people can be diagnosed appropriately
  • Explain the signs and symptoms that a doctor or person who is diagnosing themselves should look out for, and how to make sure that you reach the right diagnosis and don't confuse B12 deficiency with something else
  • Ensure treatment is tailored to the needs of the patient, and where possible, make treatment available free at the point of need

We rely entirely on donations. Although B12 supplements are funded on NHS, they are only funded for a very narrow group of conditions. We show here and in our audits that a much wider range of conditions can beneficially be treated with Vitamin B12 replacement therapy.

Finding your way around the web site

You might start with What is B12d?, and what causes it

Look at some patient testimonials and television documentaries on the subject - you may recognise your own symptoms

Take the B12 deficiency protocol test (appendix 1) or the on-line calculator (which is no longer the best way to diagnose I'm afraid), then take the protocol to your GP to discuss

If you want to understand how cost-effective B12 replacement therapy is, then this might be a good place
