NCT ID NCT06560255
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is testing whether taking high-dose fish oil supplements during pregnancy can prevent asthma and persistent wheezing in early childhood. The trial will enroll 2000 pregnant Danish women with low blood levels of omega-3s. Participants take fish oil or placebo capsules daily from week 22-26 of pregnancy until one week after delivery. The main goal is to see if this reduces the number of children diagnosed with asthma or wheezing by age 3.
