Does Fish Oil Reduce Plaque in Arteries? Facts vs Myths

Heart disease remains one of the leading causes of death worldwide, and one of its biggest contributors is the buildup of plaque inside the arteries. As awareness of cardiovascular health grows, many people wonder: Does fish oil reduce plaque in arteries?

Fish oil, which is rich in omega-3 fatty acids EPA (Eicosapentaenoic Acid) and DHA (Docosahexaenoic Acid), has been extensively studied for its cardiovascular benefits. While research suggests that omega-3s may help slow plaque progression, improve plaque stability, and lower triglycerides, they do not dissolve or completely remove existing plaque from arteries.

What Is Arterial Plaque?

Arterial plaque is a sticky buildup of cholesterol, fat, calcium, inflammatory cells, and cellular waste products. This condition is known as atherosclerosis. As plaque accumulates, arteries become narrower and less flexible, restricting blood flow to the heart, brain, and other organs. If a plaque ruptures, it can trigger a blood clot that may lead to a heart attack or stroke.

Can Fish Oil Remove Plaque?

No. Fish oil does not remove existing plaque from arteries. However, scientific evidence suggests omega-3 fatty acids may help slow plaque progression, reduce vascular inflammation, improve plaque stability, lower triglyceride levels, and support overall cardiovascular health. These benefits may reduce the likelihood of plaque rupture, which is often the cause of serious cardiovascular events. Read more: Benefits of Fish Oil and Multivitamins Together.

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. Read more: Top 10 Indian Foods to Lower Cholesterol Naturally.
  4. Prevents Blood Clots: Omega-3s improve blood flow and reduce platelet aggregation, which is crucial for individuals 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 clinical trials show that long-term use of fish oil may even reduce the thickness of arterial walls.

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 pre-existing heart conditions.
