BioStacksWhy Omega-3 for Heart
When it comes to heart, Omega-3 is one of the most key nutrients to consider. Doses vary by EPA/DHA content — always check combined EPA+DHA per serving, not total fish oil volume. EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are the two primary active omega-3 fatty acids. Absorption depends heavily on molecular form: re-esterified triglyceride (rTG) is ~70% better absorbed than the cheaper ethyl ester (EE) form common in budget supplements. In clinical studies, omega-3 supports heart health.
What dose to look for
Clinical studies typically use 1000–3000 mg of omega-3. Total omega-3 from fish oil or algae supplements. Supplements that fall short of this threshold are unlikely to match what clinical trials achieved.
What form to look for
Avoid ethyl ester — lower absorption than triglyceride. Avoid flaxseed — ala omega-3 — only ~5-10% converts to epa/dha. For best results, choose triglyceride form (rtg).
The evidence behind omega-3
Research supporting omega-3 for heart is rated as strong. Thousands of trials; meta-analyses confirm triglyceride reduction of 15-30% and modest cardiovascular benefits Learn more
