Hi caledonia,
i had Dr. Mensah's test done 3 years ago and was shown to be an overmethylator based on their tests (Low Histamine, low zinc, high copper)
I originally tried folic acid, and it was amazing. My mood improved alot and I became someone I had never been before. I was positive and happy and making friends (which is the opposite of my anti social personality) .. this lasted for 2 weeks until I started getting real bad headaches and I had to stop.
after that i read Ben Lynch's stuff saying folic acid is not the good kind and one should use methylfolate. So i tried methylfolate. Well methylfolate gave me headaches from the get go without the happy mood improvement that folic acid was giving me so I stopped it on the 2nd day....
I just watched this video
https://www.youtube.com/watch?feature=player_detailpage&v=W14kkO61Ano from Dr. Walsh, and he does touch on folates(as a general category) but nothing specific... IMO, He needs to be more specific as to which type of folate should be used by which type of overmethylator based on what findings....
Do you or anyone else know of a source of information that clearly explains the difference between different folates in relation to over/under methylation?
