How omega-3 supports heart health
Omega-3 fatty acids are true all-rounders when it comes to the heart. The most important effects at a glance:
- Better vascular function: Omega-3 supports the endothelium – the inner layer of the blood vessels – and thus ensures healthy blood circulation.
- Lower blood lipids: EPA and DHA effectively lower triglycerides and improve the lipid profile.
- Lowering blood pressure: Omega-3 can reduce blood pressure slightly but noticeably, especially in the case of high blood pressure.
- Protection against atherosclerosis: It stabilizes plaques in the arteries and prevents heart attacks and strokes.
- Better cholesterol: Omega-3 can increase the “good” HDL cholesterol.
- Anti-inflammatory: Chronic vascular inflammation is soothed by EPA and DHA.
- Stable heart rhythm: Omega-3 supports the electrical stability of the heart and reduces the risk of cardiac arrhythmia.
Studies & recommendations
The American Heart Association recommends eating oily fish twice a week. Omega-3 supplements can be useful for people at increased risk or with high triglycerides.
Studies such as the GISSI-Prevenzione study and the REDUCE-IT study show that just 1 gram of EPA/DHA a day can significantly reduce the risk of sudden cardiac death and other cardiovascular events.
