Perhaps that was a bit of an ambitious title, but that’s the general gist of this research. This paper from JAMA looks at serum vitamin B levels and the risks of developing lung cancer – but first, a little background…

The one carbon metabolism pathway is based around folate, and essentially is critical for the methylation of DNA – therefore DNA synthesis and repair rely heavily on this process. 


In the EPIC cohort studied here, the risk of lung cancer was lower in those patients with higher levels of B6 and methionine, after taking smoking into account. In certain groups (former and current smokers), a lower risk was also seen in those with higher levels of folate. Fairly strong argument to have a multivitamin a day.
