Maternal Nutrition

by Dr Louise Santhanam, General Practitioner

All new mums need to eat well for their own health now and in the future, and to make sure they are nutritionally ready for any future pregnancy. The human body is designed to breastfeed babies and you will be able to make milk for your baby without needing a special diet.

Maternal Vitamin Supplementation

Maternal Folic Acid Supplementation

The couple’s risk for a neural tube defect in pregnancy should be assessed- see NICE CKS: Pre-conception- Advice and Management.

  • All women are advised to take 400mcg of folic acid per day while trying to conceive until 12 weeks pregnant.
  • Women at higher risk of having a pregnancy affected by a neural tube defect are advised to take a higher dose of 5mg of folic acid daily until the 12th week of pregnancy. Women have an increased risk if:
    • either partner has a neural tube defect
    • they have had a previous pregnancy affected by a neural tube defect
    • they or their partner have a family history of neural tube defects
    • the woman has type 1 or type 2 diabetes mellitus
    • the woman has coeliac disease
    • the woman is obese (BMI ≥ 30kg/m²)
    • the woman is taking anti-epileptic medication
  • Women with thalassaemia trait should take 5mg of folic acid daily until the birth of the baby
  • Women with haemolytic anaemia (particularly a haemoglobinopathy e.g. thalassaemia or sickle cell anaemia) should take 5-10mg folic acid daily throughout pregnancy- seek specialist advice.
