Do omega-3 fish oil supplements actually work?

Of the supplements in this category, omega-3 fish oil has some of the strongest mainstream backing — though it's not magic.

The grounded picture

• EPA and DHA are omega-3 fatty acids your body needs and most people under-consume.
• Evidence is reasonably supportive for heart and general wellness, strongest in those with low dietary intake.
• Diet first: oily fish (salmon, sardines) is the ideal source; supplements fill a gap.
• Dose & quality vary widely — check the actual EPA/DHA content, not just "fish oil mg."

Reviewers value reliability and a clean product — "very good quality and a great value." Use fish oil to support a good diet rather than replace it, and talk to your doctor if you take blood thinners.
