Theories of 'over-methylators' and 'under-methylators' are incorrect; MTHFR gene polymorphisms can be managed with increased dietary riboflavin.

“I don't believe in over-and-under meth leaders so I think that this is a wrong I don't believe in Walsh's theories with regard to this I think that you have an mth para to convert l5 methylfolate or it converts 510 methylene tetrahydrofolate l5 methyl foley and that enzyme is going to work in a variety of ways depending on your polymorphisms your genetics and those can be accounted for with more riboflavin in your diet so I don't think you are an over methylate or per se don't think about things in terms of that”
