I've read many times that folic acid is not at all recommended and one should take Metafolin only. However, a B-Complex tablet I take has 1 mg of folic acid in it. I do take 800 mcg of Metafolin everyday too. Should I search for another b complex? I remember someone mentioning that consuming folic acid can block Metafolin, thereby making Metafolin useless. Is this true?
