I have read that it is bad to take methylfolate and folic acid together, especially if you have the MTHFR mutation. Something about the unmethylated folic acid blocking the pathways that the methylfolate needs to use.)

Is this true? And - if so, do you know of a basic multi-vitamin that does not contain folic acid? (I have found a few, but they are either extremely expensive, and/or are the "six capsules a day" mega supplements.)
