What's in the book

The book distils 46 years of clinical practice as a GP in this part of County Durham, looking after many generations of the same family.  During that time, Dr Chandy observed that

  • B12 deficiency could occur, and be cured, in people who didn’t have macrocytosis (following the presentation of his observations, university researchers have confirmed this and it’s now common knowledge)
  • B12 deficiency is far more widespread than previously thought – conditions like MS, ME, anxiety, dementia, and many others may actually be B12 deficiency, and cured by supplementing with Vitamin B12, rather than the cocktail of symptom-suppressing drugs often used today
  • Every person is unique and different, and treatment should be tailored to the individual.  Some people are fine on tablets, some people need injections, some people need injections more than weekly.  A blanket “one injection every 3 months” simply doesn’t work for some
  • Because Dr Chandy cared for patients over such a long amount of time, he could observe the progression of symptoms and the effects of treatment.  We did patient surveys and compiled medical history on over 1000 people suffering from B12 deficiency (and cured from it) over the period.

The book goes through major human life stages: fertility and pregnancy; neurological disorders; autoimmune disease; neuropsychiatric disorders; cancer and shows, citing published research spanning over 200 years, that Vitamin B12 deficiency is overlooked as a cause of misery and ill-health (and death).  And that many people could live much fuller lives if only their doctors recognised this very common condition and treated it correctly. The treatment is very cheap, and very safe.  It’s transformative.

How to read it

First time through, read the Case Studies.  You can find them by the yellow backgrounds to the text.  Get to know the people.

Then look at the Chapter Key Points.  The first page of every chapter is a diagram with the key points of that chapter.

After this, read the text.  And you can read any chapter and come back to the others.

Because the book is free or cost of printing, the charity is still very grateful for any donations which help with running costs.

June describes her suffering when doctors didn't follow the standard protocol after any stomach or intestinal operation - to offer B12 replacement therapy

New documentary out from Elissa Leonard in North America, featuring Sally Pacholok and many other internationally renowned experts.
Julia found her eyesight going as her eyes refused to focus on the same things as each other. She's been for all sorts of tests and treatment, but now that she's on B12 replacement therapy she's starting to see an improvement.
Janette first appeared in the BBC InsideOut documentary in October 2006. Since then the NHS has forced her doctor to withdraw B12 replacement therapy on a number of occasions, and she tells of her struggles with having B12 and then having it taken away.
She has bravely agreed to be filmed without her usual wig, but her memory is playing up because it is so long since her last injection.
Susan gets very tired, which isn't much fun especially as she has so much to do. Here she tells her story.
Frankie tells of how she suffered, the tests she had to endure until doctors worked out what was wrong, and what a difference it has made.
The Scottish Parliament discusses Pernicious Anaemia and vitamin B12 deficiency on Wednesday 7 March 2012.
This video is over 1 hour long and represents real political change - we are at last on our way.
Just the way it works for humans, oral B12 can make a world of a difference for your pet. My old cat Smudge chases the young cat again, climbs ladders (and climbs down herself), and is generally as fit as she was many years ago.
Donna, like so many women, wants to live a normal life. Vitamin B12 could give her that chance.
