I took Materna - I took an extra folic acid every 2nd day in the first trimester (it's not necessary, but my doctor gave me some for free and I figured why not. Folic acid is one of those vitamins that if you get too much, you just excrete it - so it's not going to harm you if you get a bit too much).
I also have calcium and iron supplements that I take as well (I usually take them on alternate days) - but if you take calcium or iron as well as the materna, it's important to not take them at the same time. Take materna in the morning, then calcium in the afternoon, and iron at night or something like that - because your body can only digest a certain amount of calcium at any one time. If you take too much, it'll just go right through you undigested. And also, calcium hinders the absorption of iron. So it's important that you take the iron by itself - with something with a lot of vitamin C like orange juice or something, NOT milk (vitamin C helps the absorption of iron). HOW you take your vitamins can be even more important than what vitamins you take because if you take them wrong, it doesn't benefit you as much...
