How EPA From Fish Oil May Calm Oxidative Stress Inside Liver Cells

Key Insight

This early lab work hints at how EPA from fish oil may support cellular antioxidant defenses.


In human liver cells in a dish, the omega-3 fat EPA flipped two tiny genetic switches at once. One switch boosted the cells' ability to build new mitochondria (the energy factories), while the other ramped up the cells' own antioxidant enzymes. Together they lowered oxidative stress. This offers a possible explanation for why omega-3 keeps showing up in liver health research, though it's lab work, not people.
