Not only is it important to get enough folate before pregnancy, you should continue to take it throughout your pregnancy both for your own health and to support your baby’s growth and development.
Unlike fat soluble vitamins (A, D, E, and K) that are readily stored in the body, folate is a water soluble vitamin so you need to get it on a daily basis to make sure you always have enough available. “This nutrient needs to be constantly replenished to maintain healthy levels,” nutrition expert said.

We recommend you to supplement better folate/folic acid:
