Omega-3s from fish outshine supplements for proven heart benefits

Many people turn to supplements for heart health, but not all deliver proven benefits. Recent findings show that some widely used products lack solid scientific backing. Experts continue to stress the importance of diet over pills for long-term cardiovascular protection.

Omega-3 fatty acids remain one of the few supplements with recognised advantages—but only when consumed through food. Studies confirm they can slow plaque buildup in arteries, reduce triglycerides, lower blood pressure, and cut the risk of heart attacks and strokes. Because of this, cardiology groups advise eating fatty fish at least twice a week.

No reliable data exists on how many Germans take Omega-3 supplements specifically for heart health. However, a 2025 survey by the Federal Institute for Risk Assessment (BfR) found that over 75% of the population used some form of supplement in the past year. Among them, 38% of women and 30% of men reported taking supplements regularly.

Other popular heart-related supplements fare worse in scientific reviews. Coenzyme Q10 shows no proven effect on heart function, blood vessels, or muscle pain linked to statin use. Meldonium, despite its use in some regions, does not appear in Russian, American, or European clinical guidelines for treating any heart condition. Authorities cite insufficient evidence as the reason for its exclusion.

For now, medical advice remains clear: whole foods provide the most reliable source of heart-healthy nutrients. While Omega-3s from fish offer measurable benefits, supplements like Coenzyme Q10 and meldonium lack strong support. Those considering supplements should consult healthcare professionals before making changes to their routine.
