The nutrient B9 (often known as folic acid) is essential during pregnancy for normal neural tube development, DNA and red blood synthesis, and cell division and it’s important for moms to consume a form of this nutrient as early as possible before they conceive, ideally at least 3 months before. Needed’s Prenatal contains a more bioavailable form of B9, called methylfolate. This form was intentionally chosen since  40-60% of women cannot efficiently convert folic acid into the more active form, methylfolate. Additionally, the dosage found in Needed’s Prenatal provides enough folate to be effective, especially for those with conversion difficulty, while still being safe for all mamas and mamas-to-be.  You can read more about this here.
