Fish Oil in Pregnancy Study

Could taking fish oil in pregnancy improve your baby's health? If you are less than 16 weeks pregnant and carrying extra weight then you may be eligible to take part.

Pregnancy bump side

We know that children of women who are carrying extra weight during pregnancy are more likely to develop health and weight problems. But women also try incredibly hard to improve their health to give their baby the best start to life.

So what can you do?

This study is to find out whether taking fish oil during pregnancy can help to prevent your baby from becoming overweight and developing problems like diabetes as they grow up.

If you are interested in taking part, simply email your name and phone number to or text "Fish Oil Trial" and your name to 027 604 5240.

What does the study involve?

We will provide you with fresh fish oil capsules or olive oil capsules to take throughout your pregnancy and until your baby is three months old.

We will assess you twice during your pregnancy at our clinic at the Liggins Institute, just opposite Auckland City Hospital at the University of Auckland.

We will also assess you and your baby for the first 12 months after they are born.

Who can take part?

We would like you to be part of the study if you are:

  • less than 16 weeks pregnant
  • aged 18 – 40
  • have a BMI of 30 – 45 (we can help you work this out if you're not sure)
  • a non-smoker who does not have diabetes

What does it cost?

It doesn't cost you anything to participate. In fact, we will reimburse you for your costs to come to our clinic in central Auckland.

How can I find out more about the study?

If you'd like to take part in the study, or you just want to find out more, it would be great to hear from you.

Simply email your name and phone number to or text "Fish Oil Trial" and your name to 027 604 5240.
