Sis, I haven't personally tried Fer-essence, pero maraming moms sa group ko ang nag-take ng ferrous fumarate with folic acid during pregnancy and postpartum, especially if sila ay anemic or yung doctor nag-prescribe dahil low iron levels. Ang combo ng iron + folic acid + B vitamins ay super common sa prenatal at postpartum supplements kasi tumutulong sa energy at sa blood health, lalo na pagka-breastfeeding. If concerned ka about side effects (dami nag-complain ng tummy issues with iron supplements) or kung okay lang for breastfeeding, better check with your OB or doctor first para sure sa dosage at lahat!
