Folic acid and planning a pregnancy

Folic acid (B9) lowers the risk of neural-tube defects in the baby, so:

• Women planning a pregnancy should take 400 mcg a day, starting at least 1 month before conception and continuing to week 12.
• In some cases (a previous affected pregnancy, certain medicines, diabetes) a doctor prescribes more — don't raise it yourself.
• Choose a dedicated prenatal formula (with iodine, iron, D); regular sports vitamins and high-dose vitamin A aren't suitable.

Agree any supplement in pregnancy and breastfeeding with your gynaecologist.
