Read our Asthma research guide →Phase 3 — Testing in thousands of people, comparing the treatment against what doctors currently use. This is the last big step before approval.
This study is testing whether fish oil supplements taken during pregnancy can help prevent asthma and other respiratory problems in young children. Pregnant women with low levels of omega-3 fatty acids (the healthy fats found in fish) will receive either fish oil or a placebo (dummy pill) from mid-pregnancy until one week after giving birth. Researchers will then follow the children for up to 6 years to see if the medication reduces asthma, wheezing, infections, and other health conditions.
Asthma and allergies are increasingly common in children, and early prevention may be more effective than treating these conditions after they develop. Research suggests that omega-3 fatty acids during pregnancy may help build the child's immune system to reduce disease risk.

You would take 4 capsules daily—either fish oil or a lookalike placebo—from around week 24 of pregnancy until one week after delivery. Researchers will collect blood samples at the start to analyze your fatty acid levels and genetics. After birth, you'll be asked to report on your child's health symptoms, illnesses, medications, and hospitalizations through questionnaires at regular intervals, with formal check-ins at ages 3 and 6 years. The study involves no office visits for your child, just your reports of what you observe at home.
