A month or so ago I confirmed that I have MTHFR mutations. Since then I have been taking L-5-MTHF and my health has begun to improve. This got me thinking about the prevalence of these mutations throughout not just CFS suffers, but also the population in general. Just how prevalent is MTHFR among people in society? I have seen some evidence that it correlates with conditions like depression, autism and other mental conditions. I couldn't find any research looking at this sort of thing in the overall population. Can anyone help me out by pointing me in the direction of any research on this sort of thing?
