Ay, sis, para sa ganitong tanong about timing ng vitamins, kailangan mo talaga magtanong sa doctor or pharmacist mo, lalo na kung specific brand yan, dahil bawat supplement may sariling instructions! Better safe than sorry, diba? Check the package din kung may written instructions, or call your OB or ang pharmacist sa pharmacy mo, super quick lang sagutin nila yan for you. Moms here might have different experiences din, so better to get the right info from the expert! Let me know kung ano sabi nila, okay?
