If you have MTHFR issues, you HAVE to take your B's and folate in methyl forms. Not to say it's dangerous otherwise but they will be ineffective. Many NDs are not real fluent in MTHFR issues — but there is a lot of info on
mthfr.net and there is also a list of "trained" specialists on the site. Not sure what they actually require for training but it led me to an awesome ND. Hope this helps.
Also—if you had a real good detox day and you're exhausted the next day, I think that's either a good sign that you did a lot of flushing or you're not detoxing too well and the gunk is "stuck". Methylization issues will compound detoxing issues so it's a great thing that you were tested. Let us know your results!
