Observing how EPA is metabolized considering genetics and sex

Determining Contribution of Sex and Genetics to DHA Synthesis Rates Over 12 Weeks of EPA Supplementation in Healthy Individuals

Phase 4 Interventional University of Toronto · NCT06975241

This study is testing how well healthy adults convert an omega-3 supplement into another important fatty acid, while looking at how genetics and sex might affect this process.

What this trial studies

This clinical study aims to investigate the metabolism of eicosapentaenoic acid (EPA) in healthy adults, focusing on how quickly EPA is converted to docosahexaenoic acid (DHA) and whether this conversion is influenced by biological sex and specific genetic factors. Participants will take EPA supplements for 12 weeks and provide blood samples to measure the conversion rates and levels of DHA and other metabolites. The study seeks to understand the dynamics of omega-3 fatty acid metabolism in relation to genetic and sex differences.

Who should consider this trial

Good fit: Ideal candidates are healthy adults with a BMI between 18.5 and 30 kg/m² who do not consume high amounts of omega-3 fatty acids.

Not a fit: Patients with chronic diseases, those on certain medications, or individuals with high omega-3 intake may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into personalized nutrition strategies for optimizing omega-3 fatty acid metabolism.

How similar studies have performed: While studies on omega-3 metabolism exist, this specific focus on genetic and sex differences in EPA metabolism is relatively novel.
