You wrote to us about a Journal article from 2009, which implies that in two academic studies from Norway, there was a higher incidence of cancer in the groups of patients receiving folic acid and also folic acid and B12.
We know from our own patients that B12 actually protects against cancer and may even cure it, so this finding surprised us. However it also surprised the authors, who are quick to point out that the preventative effect of B12 in protecting against cancer was observed in studies in USA.
Dr Chandy and myself are working on a chapter in the book on cancer, which explains how B12 is essential for consistent expressions of genes and correct transcriptions (reducing mutations). Of course it forms the basis of our interpretation of this paper, and you could accuse us of bias.
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.
The definitive and original guide to B12 deficiency, Dr Chandy interviewed by Chris Jackson of UK BBC Inside Out Team broadcast 31 Oct 2008.
Dr Joseph Chandy explains symptoms and shows the restorative effect on one patient (other patients' families have asked that we edit out their stories unfortunately)
June describes her suffering when doctors didn't follow the standard protocol after any stomach or intestinal operation - to offer B12 replacement therapy
Susan gets very tired, which isn't much fun especially as she has so much to do. Here she tells her story.
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.
Donna, like so many women, wants to live a normal life. Vitamin B12 could give her that chance.
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.
Dr Chandy was nominated for the North East Local Heroes award. The interviewer was at first surprised - people don't get awards for doing what they are paid to do - but she persisted.
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.
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.
