Dr Walsh query

I have pyroluria & have had big improvements on the pyroluria protocol.

However I am getting more interested in the wider picture - e.g. to see if I am over-/under-methylated as well, & to see what other imbalances there might be.

Re biochemical imbalances, Dr William Walsh seems to cover the waterfront better than most. But the most up-to-date COMPREHENSIVE article of his that I can find is from round 2003:

I don't want to miss the research that's been done in the last decade or so. Does anyone know of a more recent rundown of the various biochemical imbalances (by Walsh or anyone else)?

Thanks to all...
