Do prenatal vitamins contain enough amount of folic acid or i should take additional folic acid for the health of the baby?

Consider L-5MTHF: Prenatal vits. Contain enough Folic Acid for most people but about 1/3 of people have difficulty converting Folic Acid (which is synthetic) to the active form, l-5-methyltetrahydrofolate (l-5-mthf) and 10% can 't convert it at all. A test for the mthfr gene is the only way to know for sure but it doesn't hurt to take 400 mcg of l-5-mthf to be safe and to eat dark leafy greens & other diet sources.
