MTHFR or MethylTetraHydroFolate Reductase Deficiency or as I like to call it the MotherF**ker defect (yeah, I know, rude, politically incorrect but damn if this doesn't screw me up good).
I have at least two defects in my MTHFR genetic pathway. This inhibits methylation and allows homocysteine to build up in my system. Here is a series of vids explaining the genetic mutations and a treatment protocol to aid with symptoms. Interestingly I've added a lot of the supplements already and those are the ones I've noticed have done me the most good. I'm only missing five off his entire list.
Sorry, I tried to embed the vids but it didn't work for some weird reason. If the links don't work just search for Dr. Neil Rawlins on the YouTube page and they will pop up.
