If you have a family history of NTD you should be tested for MTHFR mutations. Its a relatively new discovery but it completely explains why folic acid doesn't work for some people. People with a MTHFR mutation can't break it down and use it very well. They use folate just as well as anyone else but it isn't found in most supplements because its cheaper and easier to add in folic acid. A lot of good folic acid does the 17% of Americans who can't use it!

The reason for taking folic acid before conception is typically that a lot of pregnancies are unplanned and if you start taking it after you realize you're pregnant, it might be too late for it to have a benefit. It is still important up until the fetal neural tube is formed... and can't hurt after that.
