Congratulations Anamaj! Btw, I'm also on Materna which I bought from Canada as well as some Folic acid (1mg). When I asked my OB (Philip Ho) about this, he seemed pretty relaxed and said "take both - why waste it?". I think it's dangerous to take too much of certain vits - like Vit A - but from what I've read and heard, extra folic acid is just excreted with no harm to bubs. During the first trimester (I'm now 18 weeks), I took Materna when I could (ie. non-queasy days) and just folic acid (much smaller pill) on other days when I couldn't stomach Materna.
