Zincofer + folic acid lagi, boleh ke?

Hi mommies.. saya baru pregnant nak masuk 5week.. sebelum ni biasa makan folic acid 400mcg. Sy hb low.. Kalau sy mkan zincofer yg ad 1000mcg folic acid perlu ke sy stop folic acid tablet 400mcg tu? Tak overdose ke sebab sy baca recommended for prengant women is 500mcg a day.
