Hi po! Quatrefolic (folic acid) is definitely important para sa TTC at pregnancy kasi tumutulong sa baby's development, pero honestly, maraming vitamins ang may folic acid na recommended ng doctors, like prenatal vitamins with methylfolate or regular folic acid supplements. A few of my mum friends took specific prenatal vitamins during TTC, pero ang best talaga is to check with your OB kung which one is right for you, since they'll consider your full health picture. Good luck sa journey mo!
