this collation of information is a good "summary" - most of all it explains why one week you can feel fantastic, and then the next week struggle and feel like crap.
you dont have to be diagnosed with MTHFR or Pyrrole for this information to be useful. Once MC is active our bodies are a very sensitive complex environment and getting the right supplements in the right forms is a big part of attaining wellness.

one section of note:
for those that swap from B12 supp to Active B12 supplementation
things may get worse before they get better,
Has anyone else had increased inflammation from restarting the methylation cycle?
The Carmen Wheatley “Scarlett Pimpernel” papers I, II and III deal with this very issue. That with b12 there is first an increase in inflammation and then a neutralizing of the nitric oxide leading to a decrease in inflammation. This appears to happen as cell formation picks up with methylation starting up. There is no need to take prednisone. The inflammation will run it’s course and inflammation and pain will decrease. I had a lot of pain which wasn’t controlled by multiple medications. The pain decreased perhaps 90% allowing all but one medication to be discontinued. I had been taking 2400mg/day of ibuprofen. 9 months after starting mb12 the inflammation was gone and ibuprofen made no difference any more.
9 months after starting mb12 I was able to discontinue/taper Dilantin (for neurological pain and some spasm control). 9 months after starting mb12 I was able to start tapering benzos. 9 months after starting mb12 I was able to discontinue albuterol, Compazine suppositories, antihistamines, theophyllin, an anti-narcolepsy med and probably a few more in there. It took about 9 months to reach that point. However, some specific pains started fading by year 10.
