400 ug: This is the minimum dosing for routine pregnancy without any other circumstances that might require more such as elevated homocysteine, twins, or history of neural tube defect.

5 mg.: Most of the severe (not all) fetal malformations can be prevented with preconceptional Folic Acid (for at least 3 months before conception). Expect 75% of cardiac defects and >90% of neural tube defects to be prevented thus.
