This site acts as a hub to bring all the key information and journals on vitamin B12 deficiency together in one place. It originates in the UK and holds information particular to the NHS, however, my aim is to give a direct route to factual information, wherever you are in the world. None of the information contained within this site is hidden behind paywalls.


The main aim of the site is to help patients to gain a greater understanding of the condition, to acheive a correct diagnosis and correct treatment from their doctor. Education is the key, if you want to learn more please see our conference page.

All pink text throughout the site will take you to journals or further reading.

If you think you are B12 deficient please visit the What to do next? page. There is also a page to help with writing to your doctor should the need arises.

I would like to take this opportunity to express my sincere thanks to both Sally M. Pacholok R.N. and Pat Kornic for their support in creating this website. Click here for Pat's support group.

Sally Pacholok is a name recognised around the world for the excellent book 'Could it be B12?'  Co authored with her husband Dr. Jeffrey Stuart, this book's 1st edition was published in 2005 and has saved many lives. Text from the book is used with permission throughout this site. An award winning feature film has been made based on Sally's life you can now download the film from Vimeo.

Issues that patients face


Simply watching the first 5 minutes of this documentary film will make it clear just how serious B12 deficiency is and how misdiagnosis can occur. The education of all clinicians on this very common condition is critical.

Below is a short film made for a petition which asks the Department of Health for testing for B12 deficiency to be added to a Full Blood Count. To sign and share the petition please click here.





Many with this condition feel they have no alternative but to resort to self treatment. They purchase their injectable B12 from the many countries where it is legally sold over the counter. Faced with doctors who refuse to treat patients adequately, self injecting is often the only route to health. If we could buy injectable B12 over the counter in the UK it would change lives, please sign the petition below.


Thank you for visiting the site.



Tracey Witty, a patient living with B12 deficiency.
