Cod liver oil is a type of fish oil supplement.

Like regular fish oil, it's high in omega-3 fatty acids, which are linked to many health benefits, including reduced inflammation and lower blood pressure (1, 2).


It also contains vitamins A and D, both of which provide many other health benefits.

Here are nine scientifically supported benefits of cod liver oil.

2. May Reduce Inflammation

Inflammation is a natural process that helps the body fight infections and heal injuries.

Unfortunately, in some cases, inflammation can continue at a low level for long periods of time.

This is known as chronic inflammation, which is harmful and may increase the risk high blood pressure and several diseases, such as heart disease (8, 9, 10).

The omega 3-fatty acids in cod liver oil may reduce chronic inflammation by suppressing the proteins that promote it. These include TNF-α, IL-1 and IL-6 (1).

Cod liver oil also contains vitamins A and D, which are powerful antioxidants. They can reduce inflammation by binding and neutralizing harmful free radicals (11, 12).

Interestingly, studies also show that people who are deficient in vitamins A and D are at a greater risk of chronic inflammation (13, 14, 15).

Summary: The omega-3 fatty acids in cod liver oil may help suppress proteins that promote chronic inflammation. Cod liver oil is also a great source of vitamins A and D, both of which have antioxidant properties.

People often look at issues through the prism of their own particular political identity — and have probably always done so.
