First seen Jul 21, 2026 · Last updated Jul 22, 2026 · Updated 1 time

Summary

This study tests whether taking omega-3 fatty acid supplements (fish oil) can reduce the amount of fat in the liver of people with nonalcoholic fatty liver disease. Participants take either fish oil or a placebo oil (safflower oil) daily for a period of time. The main goal is to see if liver fat decreases, measured by a special MRI scan.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
fish oil (omega-3 fatty acid) dietary supplement
What this could lead to
If it works, this could point toward a simple dietary supplement to reduce liver fat in people with nonalcoholic fatty liver disease.
What could go wrong
This is a small, early study with only 30 participants, so results may not apply to everyone. The supplement may not reduce liver fat more than the control oil.
