None of them is a study in people. 1 was a study in animals, and none was only in cells in the lab. 1 paper is a review that sums up other studies. 1 new study in people is running or will start soon, say the trial registers.

Verdict
Omega-3 fatty acids (fish oil) has been studied for aortic stenosis in animals, not yet in people.
Unproven means: it was only tested in animals or cells, or there is too little or mixed data from people. How we rate claims
What this means for you: Results in animals or in cells often do not hold in people. Do not stop or change your medicines because of it. Ask your doctor before you start taking it.
