Recent advances in policy and practice translation of the evidence for additional omega-3 fatty acids and prematurity.

Purpose of review
This is a review of the most up-to-date research on the effectiveness of omega-3 fatty acids for reducing the risk of prematurity in well nourished women with access to high-quality obstetric care. It will provide an
overview of the translation of the evidence on omega-3 screening into policy, and the latest research on how to implement the policy into practice.

Recent findings
Findings of the included clinical studies support that omega-3 supplementation for women with a singleton pregnancy who have a low omega-3 status reduces the risk of early preterm birth.

Summary
There is evidence that screening and providing appropriate advice to women with a singleton pregnancy who have a low omega-3 status can reduce their risk of early preterm birth, and avoiding supplementation for women who are replete will avoid unnecessary supplementation and potential harm.
