Summary

This study looks at whether genetic differences affect how omega-3 supplements influence heart disease risk factors like cholesterol and blood pressure. Researchers are giving 200 healthy adults omega-3 capsules daily and measuring changes in blood lipids, blood pressure, and gene activity. The goal is to understand why some people may benefit more from omega-3s than others.
