Oo, safe naman ang prenatal vitamins para sa buntis, yan talaga ang purpose nila, to support you and baby during pregnancy! A few of us moms took them regularly, at honestly nag-help sila especially para sa folic acid at iron na kailangan mo. Best pa rin to check with your OB though para sure na ang specific brand or dosage ay okay for you, lalo na kung may ibang vitamins or supplements ka nang intake, para walang interaction. Mabuti na lang nag-invest ka sa health mo at baby mo, sis!
