Giving You Back YOUR Life

Worried about Cancer?

Dear Stephanie

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. 

  1. Folic acid has been highlighted as potentially dangerous as a supplement, because the synthetic form used for supplementation (ie not natural folate) may not be the biologically active form and may deplete various coenzymes because they are a different form.  If you know a lot about biological molecules, you will know that not only do they come in right-handed and left-handed forms, but there are often other differences (for example, phytocobalamins are as toxic to B12 metabolism as Carbon Monoxide is to oxygen metabolism (respiration) – they substitute and block the transport or metabolism.
  • In the paper you cite, the level of folic acid supplementation is only just below the maximum tolerated level (the paper explains this).  The maximum level is for folate ie natural B9, not taking into account that whilst many folic acids are acceptable to the body, there’s no mention of the form used in these trials and this paper.
  1. If you check the tables, the data clearly shows that B6 supplementation gives people the wanderlust – during the trial 3x as many people decided to emigrate from Norway and lost to the trial.  But the authors didn’t highlight that because unfortunately it doesn’t make good clickbait.  The data also show that B6 by itself is extremely effective against cancer.  But the statistical analysis combines groups and says that this isn’t a real effect
  2. We know from our work that B12 can (often does) restore the body’s ability to absorb folate.  This could cause problems if the liver coenzymes are tied up with inappropriate forms of folic acid.  We found that (by checking blood levels) within a few months of supplementing with both B12 and folate, we stopped the folate.  From then on, we stopped supplementing folate even though blood levels of folate would quickly restore to healthy levels but using natural folate instead of synthetic folic acid
  3. Our own work shows that B12 reduces incidents of cancer, although this was most pronounced with GI and rectal cancers.  The authors of the paper you cite point out that their Norway study is very different from all of the studies of work done in USA.  They haven’t even said “more research needs doing” which researchers always say, which makes me think they are a little embarrassed about how they interpreted the data.  Certainly looking at their own data presented in the published tables in the document, I don’t come to the same conclusions

The local MP (Grahame Morris MP for Easington - who was a BMS (BioMedical Scientist) in the labs at Sunderland Royal Infirmary) interviews people with B12 deficiency to hear their story (August 27 2010). Here Jane describes the symptoms, and how she can't wait for her next B12 injection (in fact, she knows that she needs injections every 2 weeks because she's keeping a diary of the symptoms). We're restricted how often the GP can give injections, which is why we want to raise awareness.
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)
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.
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.
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.
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.
June describes her suffering when doctors didn't follow the standard protocol after any stomach or intestinal operation - to offer B12 replacement therapy
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.
Donna, like so many women, wants to live a normal life. Vitamin B12 could give her that chance.
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.
