Any drug causing: birth defects is separate from taking a supplement to support neurological development in pregnancy. Most supplements don't and aren't designed to prevent against birth defects. If you are concerned about this, discuss it with your OB/GYN doctor, and get a full evaluation of what you're taking, and what your concerns are. So, you can have piece of mind. Taking too much folic acid is not wise too.

Also 84% of the US population is not able to process synthetic folic acid--we must take the "end product" instead: L-methylfolate. I prefer a compound from Bellevue pharmacy that is covered by most insurance, while the rest are expensive and rejected by insurance companies as "medical foods". To a person with a MTHFR defect (677 or 1298), regular folic acid is close to "poison".

Lamictal is FDA: Pregnancy Category C. It would not be safe to assume that use of Folic Acid would be protective for potential side effects related to lamictal.

Test for MTHFR 677 & 1298, if positive, you need 15mg of L-methylfolate daily when taking lamicta. If negative (only 16% of the US population are), then regular folic acid is okay. Most of us have a defect in our folate metabolism that requires the special stuff-my fav is a compounded one from Bellevue pharmacy called "S8", covered by insurance!!!
