Does Fish Oil Reduce Plaque in Arteries?

Does Fish Oil Reduce Plaque in Arteries?

Fish oil, rich in omega-3 fatty acids (EPA and DHA), is known for its heart health benefits. While it may not completely remove existing plaque in arteries, it can help reduce the risk of further plaque buildup and slow the progression of atherosclerosis (hardening of the arteries).

How Fish Oil Helps:

1. Reduces Inflammation: Omega-3s help lower inflammation in the blood vessels, which is a key factor in plaque formation.
2. Lowers Triglycerides: High levels of triglycerides increase the risk of arterial plaque. Fish oil helps reduce these levels significantly.
3. Improves Cholesterol Balance: It may slightly raise HDL (good cholesterol) and lower LDL (bad cholesterol), reducing the chance of new plaque forming.

Prevents Blood Clots: Omega-3s improve blood flow and reduce the risk of clotting, which is important for people with narrowed arteries.

What Studies Say:

Research suggests fish oil may not directly “clean out” arteries, but it can stabilize existing plaque, making it less likely to rupture and cause heart attacks or strokes. Some studies show that long-term use of fish oil may even reduce the thickness of arterial walls.

How to Take It:

Recommended Dose: Typically 1000–2000 mg of combined EPA and DHA per day.

Sources: Fatty fish (like salmon, sardines, mackerel) or high-quality fish oil supplements.

Important Note:

Fish oil is not a quick fix, but a supportive tool for long-term heart health. A healthy lifestyle — including a balanced diet, exercise, quitting smoking, and managing stress — plays a key role in reversing or slowing artery damage.

Always consult your doctor before starting fish oil supplements, especially if you’re on blood thinners or have heart conditions.
