Who could benefit from this research

Could help

Adults with atherogenic dyslipidemia who are eligible for omega-3–related interventions.

Less likely to help

People without dyslipidemia or those not fitting the study’s lipid profile criteria may not benefit.

What this research studies

Researchers will compare the biological effects of EPA and DHA at a therapeutic dose in adults with atherogenic dyslipidemia to understand how each fatty acid influences thrombogenesis and HDL behavior. The study will examine platelet activity, thrombosis-related pathways, and how HDL particles mediate these effects to explain inconsistencies seen in prior omega-3 trials. By conducting a head-to-head clinical assessment, investigators aim to uncover mechanism-based differences that could inform personalized omega-3 recommendations. Participants will contribute blood samples and clinical data to reveal how EPA and DHA differently modify cardiovascular risk factors. This proof-of-concept work could guide future trials and dietary guidance for reducing heart disease risk.

Why it matters

Potential benefit: If successful, the findings could lead to more precise omega-3 recommendations and improved strategies to lower cardiovascular risk in people with dyslipidemia.

How similar studies have gone: Previous studies show mixed results; this head-to-head comparison is a novel approach to clarify differential effects.
