Omega-3s might help calm down inflammation in the body, which could make life easier for people with joint pain or autoimmune diseases.

Omega-3s, like those in fish oil, help your body make natural chemicals that shut down inflammation when it’s no longer needed—kind of like hitting the 'off' switch after a fire alarm goes off.

Taking fish oil supplements (which have EPA and DHA) might help calm down skin inflammation by boosting natural healing chemicals and lowering inflammation signs, but sometimes it works really well and other times it doesn’t — it’s inconsistent.

Taking a daily omega-3 supplement for 3 months can calm down the immune system in your fat tissue, even if you're at a normal weight—like turning down the volume on inflammation signals that don't need to be so loud.

Eating too many omega-6 fats (like in vegetable oils) compared to omega-3 fats (like in fish) can make your body more inflamed, which can damage your blood vessels and lead to clogged arteries over time.

How fish oil is made and packaged can change how well your body absorbs it, whether you like taking it, and how much it might help your health.
