Omega-3 / DHA (Fish Oil) and Heart Failure: Latest Research 2026

This page summarizes the current state of scientific research on Omega-3 / DHA (Fish Oil) in the context of Heart Failure as of 2026. The field evolves rapidly — this is a research summary, not medical advice. Consult your cardiologist for personalized guidance.

Compound Overview

Omega-3 / DHA (Fish Oil) (Fatty Acid / Anti-inflammatory) — Prescription (Vascepa, Lovaza) for triglycerides; supplement OTC

Mechanism of action: EPA/DHA compete with arachidonic acid; reduce pro-inflammatory eicosanoids; DHA structural brain component; SPM production

Current evidence level: Strong cardiovascular data (Vascepa REDUCE-IT); VITAL trial: 17% cancer mortality reduction; ALS supportive
