Question

Can fish oil supplements improve psoriasis symptoms?

No name
No state given

Answer

Psoriasis is less common in populations whose regular diet includes cold-water fish containing omega-3 fatty acids. But study results have been mixed as to whether fish oil supplements can reduce inflammation and improve psoriasis signs and symptoms, such as itching and scaling. The latest findings suggest that fish oil delivered intravenously reduces psoriasis symptoms better than fish oil supplements taken by mouth.

Side effects of high-dose fish oil supplements can include a fishy aftertaste, heartburn and nausea. Dosages greater than 3 grams a day can affect blood clotting, increase your risk of bleeding and decrease blood pressure. This may be of particular concern if you're taking blood-thinning medication or high blood pressure medication.
