I believe that Yasko and her supplement-selling business has largely invented methylation disorders. I haven't see much proof that they exist on anywhere near the scale which would be indicated by many of the claims.What i specifically wanna know Val is what you believe is causing methylation disorders.
How is a methylation disorder scientifically defined? How is it diagnosed? What are the actual effects? Is there research showing that it's common at anywhere near the levels which some people report here?
It's mostly just assumptions at this point, many of which (regarding SNPs at least) are clearly wrong.
