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.  NHS will fund B12 for some patients - directly via your doctor. We show here and in our audits that a much wider range of conditions can beneficially be treated with Vitamin B12 replacement therapy.  We are not able to send B12 to people.  This is because we describe the symptoms of B12 deficiency on this site.  We do not have B12 and we do not send it to anyone.

People with B12 deficiency exhibit a range of symptoms, which can include weakened immune system.  Therefore we're no longer holding meetings until the danger from COVID-19 is over.  Please email Dr Chandy on notifications@b12d.org with your symptoms, question, and phone number (he will usually email but may call you back) and/or download or buy the book "Vitamin B12 deficiency in clinical practice".

Please note that doctors can request copies of the full 299 page book "Vitamin B12 deficiency in clinical practice" for free by sending us an email.  See blog (at the bottom of the page) for 9 July 2019
