Salmon oil showdown: can a less processed supplement boost heart health?
NCT ID NCT06802068
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed study tested whether a natural, unprocessed salmon oil supplement (CARDIO®) improves omega-3 levels and heart health markers better than standard cod liver oil. 96 healthy adults aged 40-80 took one of the two oils for 14 weeks. Researchers measured changes in omega-3 index, inflammation, cholesterol, and diabetes risk markers.

- What this could lead to
- If it works, this could show that a less processed salmon oil is better absorbed and offers more heart health benefits than standard omega-3 supplements.
- What could go wrong
- This is a small, completed study in healthy adults, so results may not apply to people with health conditions. Past omega-3 supplement studies have shown mixed benefits.
