There has been some published papers suggesting that folic acid may compete for methylfolate at the blood brain barrier.
I haven't read anything recently however.... but from what I read not too long ago, this was not 100% proven.
It is a problem because folic acid is supplemented in many US foods now. If true, then there has to be some way to minimize the folic acid contribution. So it is not just the multivitamins that would be worth looking at (in the US).
I'll look into this or you can as well... My first stop will be MTHFR.net. If anyone has an answer, he will.
