葉酸 is important for mother (having baby), but from a Taiwan website (
http://www.healthwomen.com.tw/fe.htm), which says Vitamin A is DANGEROUS to babies. I'm confussed.... I want to give my wife Materna (product of Wyeth,
http://www.wyeth.com.hk/b5/products/nut_materna.asp), but which contains Vitamin A 1500 IU. Please let me know if I should give my wife the Materna tablets?
