I want to clarify that I don't think methylation supps are not helpful. Improving methylation, silencing bad genes, strengthening detox and raising antioxidant status is important in ME. In some cases doing this might even lead to remission, if the root cause
is faulty methylation. But I suspect that in most cases, there is more to the story than methylation.
Here is an example of the set point theory I am talking about:
So here we see that gut microbiota regulates the set point of the HPA axis. Will methylation supps change that? Of course, gut microbiota is not the only factor regulating the set point of the HPA axis.
And the HPA axis is just one subsystem, though it is an important one. There are surely other biological subsystems, each with similar interacting set points. The immune, neurological and endocrine subsystems all interact heavily.
