Typical fish oil side effects include digestive symptoms such as stomach upset, belching or a fishy aftertaste, and looser stools. Some individuals report nausea or a feeling of fullness.

Check for fish or shellfish allergies, and choose a reputable product with good quality controls.

Warning signs requiring medical attention include unusual or prolonged bleeding, severe allergic reactions, chest pain, or persistent severe gastrointestinal symptoms. If these occur, discontinue use and contact a healthcare provider. For ongoing use, periodic check-ins with a clinician can help ensure that your approach remains appropriate for your situation.
