Omega-3 fatty acid supplementation in pregnancy-baseline omega-3 status and early preterm birth: exploratory analysis of a randomised controlled trial.

18 Feb 2025

This study explored whether measuring omega-3 fatty acid levels in early pregnancy can identify women at risk of early preterm birth and determine who might benefit from omega-3 supplementation.

Researchers analysed blood samples from pregnant women around 14 weeks' gestation to assess their omega-3 status. They found that women with low omega-3 levels (≤4.1% of total fatty acids) had a higher risk of early preterm birth. For these women, omega-3 supplementation significantly reduced this risk.

Conversely, women with higher omega-3 levels (>4.9%) had a lower risk of early preterm birth, and additional supplementation in this group was associated with an increased risk.

The study suggests that assessing omega-3 status in early pregnancy can help tailor supplementation recommendations to reduce the risk of early preterm birth.
