The Omega-3 and Infant Allergy Connection

Posted on

Omega-3 fatty acids, lauded for their numerous health benefits, have come under the spotlight in recent years for their potential role in reducing infant allergies. With allergic conditions being of significant concern for many parents, any strategy to mitigate such risks is certainly welcome news.

Let's delve into the research around omega-3 supplementation during pregnancy and its link to a reduced risk of allergies in infants.

Allergic Diseases and Omega-3

Studies suggest that omega-3 supplementation during pregnancy may play a role in reducing the risk of certain allergic diseases in children. A pivotal randomised controlled trial published in the Journal of Allergy and Clinical Immunology indicated that fish oil supplementation in the last trimester of pregnancy reduced the risk of persistent wheeze or asthma in offspring.

Impact on Eczema

Eczema, also known as atopic dermatitis, is an inflammatory skin condition affecting many infants. Some evidence indicates that omega-3 supplementation could potentially reduce the risk of this condition, given its anti-inflammatory properties.

Food Allergies: What Does The Research Say?

When it comes to food allergies, the evidence is more mixed. Some research points towards a protective effect of omega-3s, while other studies do not find a substantial association. Given the gravity of food allergies in some children, this area certainly merits more rigorous investigation.

How Do Omega-3s Work?

The exact mechanism by which omega-3 fatty acids might counteract allergies remains a topic of investigation. However, the prevailing theory revolves around their ability to modulate immune responses. Omega-3s can tip the balance between pro-inflammatory and anti-inflammatory agents in the body. This balance may lead to a child's immune system being less hyper-reactive, thereby potentially reducing allergy risks.


The benefits of omega-3s for both the mother and the developing foetus (like supporting brain and eye development) are well-established. We recommend Zita West VItal DHA, which has been formulated specifically for fertility, pregnancy and the postnatal period.

While promising, the link between omega-3 supplementation during pregnancy and reduced risk of infant allergies still requires further exploration. Every pregnancy is unique, and what works for one individual might not work for another. Hence, always ensure you're making informed decisions by seeking advice from health professionals.
