Some of the things people use for sways such as green tea may block folic acid (and indeed, I was drinking a very small amount of green tea when I conceived my son with the NTD). Excess sodium, herbal supplements (which people take against my wishes very often) and the things like baking soda drink, Ural, Alka Seltzer some people insist on using also block and cause excess excretion of folic acid and folate.
I have the blue sway recommendation for FA/folate set at that level to protect against any neural tube defects even with the green tea, high sodium, herbs, and other things people may ingest over my wishes. Also in case of twins, which may need that higher level of folic acid. Boys may even need somewhat more to begin with, since they need more of all nutrients. It just seems like a good idea to me and my research indicates it is fully safe if you take it as directed and wean off at the end of the first trimester.
Most of us who have baby with NTD are told to take 4000-5000 mcg with subsequent pregnancies. It is not believed harmful for anyone without the MTHFR mutation to take folic acid in this amount, and it is fine for everyone to take folate in that amount (so if you are worried about it, just use folate, it can't harm you.) during the first trimester. You will just urinate out any excess. After that point taking extra FA may be harmful but we have you wean off at that point to the amount in a prenatal.
