Fish Oil Repairs Blood Vessels

Maylin Rodriguez-Paez RN

You’re probably aware that fish oil is heart-healthy, but do you know exactly why?

According to new research, an extremely interesting mechanism is at play.

In a recent study, scientists found that fish oil acts like a “repairman” to mend broken blood vessels. The results were published in the American Journal of Clinical Nutrition.

Fish Oil Boosts Production of Stem Cells that Repair Blood Vessels

Previous studies show the benefits of fish oil on heart health, but the exact mechanisms are not entirely understood. Scientists from the University of Reading tested the effect of fish oil on two new markers for heart disease: endothelial progenitor cells and endothelial microparticles.

The endothelium is the inner lining of blood vessel walls. Poor endothelial function is associated with atherosclerosis, high blood pressure, and heart disease. Endothelial progenitor cells (stem cells that turn into endothelial cells) repair damaged blood vessels.

A higher number is thought to decrease the risk for heart disease. On the other hand, endothelial microparticles are released by damaged blood vessels and correlate with an increased risk for heart disease.1

In this study 84 participants at increased risk for cardiovascular disease were randomized to receive 1.5 grams of fish oil daily or were part of a control group for eight weeks.

At the end of the trial the participants taking the fish oil had 24-fold higher amounts of endothelial progenitor cells and 20% less endothelial microparticles.1

The results indicate that fish oil supplementation leads to blood vessel repair, as witnessed by the increase of endothelial progenitor cells, and resulted in less endothelial damage. These results add to the growing benefits of fish oil.

Supplementing With Fish Oil May Help Prevent Heart Disease

Endothelial function is affected by disease, lifestyle choices, and aging.

Methods to preserve endothelial function, in this case fish oil, present a unique opportunity to reduce the risk of heart disease, the number one killer in the US and in the world today.

Are you living to prevent it?
