Is It Safe To Supplement Fish Oils (Omega 3s) During Pregnancy?

4 Nov

This is a question I get asked fairly often, so I thought I would place the answer here for everyone.

Omega-3 fatty acids are vital during pregnancy.  They are essential both for your wellbeing and the development of the baby growing inside you – particularly their nerve and brain development. 

However, you must select your omega-3 supplement very carefully as many brands are not as pure as you may think, or they may claim. 

(I do recommend specific brands – please contact me at for details)

Some people make the mistake of supplementing cod liver oil during pregnancy, which can be dangerous as these supplements can contain excess levels of retinol. 

Omega-3s can be provided by oily fish, however this should not be done as an alternative to supplementing.  When eating a diet high in oily fish it is important to remember two things.  Firstly, that tuna (a common fish choice) has a high mercury content and so should be limited.  Secondly, that all fish are forced to live in the world’s polluted waters, and should therefore also be eaten 2-3 times a week as a maximum.

And so, not only is it safe to supplement omega-3 fatty acids during pregnancy, it is vital that you do so.
