The claim
Posts online say that omega-3 fatty acids (fish oil) helps with coeliac disease.
Where research stands
We found 4 published papers on omega-3 fatty acids (fish oil) and coeliac disease. They were published between 2011 and 2024. None of them is a study in people. None was a study in animals, and 1 was only in cells in the lab. 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 coeliac disease only in cells in the lab.
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.
