Ahhh, momsh, that's a medical question so importante talaga, please check with your OB muna bago mag-switch ng anything, okay? Hindi ko kayang mag-recommend ng replacement kasi bawat prenatal supplement ay may specific reason kung bakit inprescribe ni doc. A few of us moms learned the hard way na may timing at combination din ang supplements during pregnancy, so better safe than sorry talaga! Maybe ask your OB if may available alternatives dyan sa area ninyo, or online options? They'll know best what's safe for you and baby.
