What’s the Difference Between Cod Liver Oil and Omega 3?

Both Cod liver Oil is an extraction from the liver of Cod fish. The liver of cod fish is pulverized with water until the oil shows up on the surface. This oil is then separated and distilled for any impurities. People use Omega 3 and cod liver oil as interchangeable words.

Both are healthy supplements for the body, and the primary difference between them is that cod liver oil also contains vitamin A and vitamin D.

Fatty Acid Functions in Human Body

Fatty acids are crucial dietary constituents as our body cannot manufacture them. Fish oil is a significant source of polyunsaturated fatty acids and is necessary for building cell membranes. All of the cells in our body need fatty acids for gene transcription in the replication of DNA and RNA, and they are also forerunners of cytokine.

Many complex and interconnected systems in our body use fatty acids as an energy source. Therefore, it is essential to intake fatty acids in your diet to maintain a healthy body. The two most salient Omega 3 fatty acids our body needs are EPA & DHA.

What is Cod Liver Oil:

Cod liver oil is an extraction of oil from the liver of Cod fish. Both cod liver oil and Omega 3 have many benefits due to EPA and DHA in them.

Benefits of EPA and DHA on Cardiovascular System

EPA and DHA both have positive effects on the cardiovascular system. If you are a heart patient or at risk of developing heart disease, you can reduce the chance with the help of EPA and DHA. Here are a few benefits you can get by using EPA and DHA in your diet.


High blood pressure is dangerous for your heart. It can become a fatal condition if you do not contain it. The excessive flow of blood in your arteries can make them lose their elasticity, and the loss of elasticity can decrease the flow of blood in your body. Your heart has to work harder to push blood into your body. High blood pressure can result in heart diseases and heart failure.

Many pieces of research confirm that to control your heart rate and blood pressure, you can use DHA supplements.

Cardiac Diastolic Filling

Cardiac Diastolic dysfunction is the stiffening of the heart’s chambers. If you have chronic hypertension, you may contract cardiac-diastolic dysfunction. Due to constant high blood pressure, your left ventricle may be dysfunctional and have a hard time filling blood.

You can feel out of breath and gain significant weight due to this dysfunction. A clinical trial conducted in 2002 suggests that combined EPA and DHA consumption can significantly improve systematic arterial compliance in humans.

Inhibits Inflammatory Processes

Both EPA and DHA reduce inflammation in our cardiovascular system. Body inflammations can increase the risk of heart diseases. DHA targets inflammation by lowering the genetic sequence of four types of pro-inflammatory proteins. On the other hand, EPA only works for one pro-inflammatory protein.

By reducing the inflammation in your system, EPA and DHA reduce the risk of heart diseases.

Difference Between Cod Liver Oil and Omega-3

Both Cod liver oil and Omega 3 contain EPA and DHA. The only thing that separates them from each other is the presence of Vitamin A and Vitamin D in cod liver oil. Due to this difference, there is a slight difference in the benefits of cod liver oil and Omega 3. Below we will state the difference in benefits in detail.

The difference in Benefits:

Omega 3 intakes can improve your brain’s cognitive function, and it helps improve your memory. Omega 3 enhances the blood flow to the brain, which reduces the risks of dementia.

Omega 3 supplements or dietary consumption is very beneficial for the human body as it increases muscle elasticity and decreases the risk of muscular degeneration and glaucoma. It also helps with multiple eye diseases and dry eye syndrome. In the digital era where blue light is causing dry eye syndrome to every other person, it is beneficial to have an Omega 3 reserve in your diet.

Cod liver oil can help you improve your joint health. It can reduce your joint pain with its anti-inflammatory effects. A 24-week research study shows that cod liver oil reduces pain. The patients who used cod liver oil supplements used fewer painkillers for their pain.

The Difference in Sources:

The sources of cod liver oil are fish rich in fatty acids. The cod liver oil comes from anchovies, tuna, herring, and salmon.

The food chain of omega-3 fatty acids starts from microalgae that are a means of sustenance for phytoplankton. Fish consume phytoplankton to get Omega-3 fatty acids.

The source of Cod Liver Oil is the liver of Pacific and Atlantic codfish. While the origin of Omega 3 is vegetable oils, walnuts and other nuts, leafy vegetables, flax seeds and animal fats.

The Recommended Dosage of Omega 3 and Cod Liver Oil

As explained above, cod liver oil contains vitamin A and vitamin D.

Vitamin D helps absorb calcium in the bones and improves the body’s defence system. However, cod liver oil has a lower concentration of Omega 3 than Omega 3.

The recommended dosage of Omega 3 and cod liver oil differs based on Age.

From ages 5 to 14, take 500mg daily. Adults under 40 should increase their dose to 1000mg daily. However, people over 40 must take 2000mg per day.

Cod liver oil’s dose should not increase by 2000mg due to its vitamin A range. The EPA and DHA’s daily dose should be 200mg to 300mg in pregnancy.
