Cod Liver Oil

Rich sources of omega-3 fatty acids beneficial to bodily functions and can help prevent illnesses.


Cod liver oil and fish oil are rich sources of omega-3 fatty acids beneficial to bodily functions and can help prevent illnesses. They come from different fish sources; cod liver oil is most commonly extracted from Pacific and Atlantic cod, whereas fish oil is from the flesh of fish such as mackerel, herring, tuna, and salmon.

Both cod liver oil and fish oil contain EPA and DHA, which are long-chain omega-3 fatty acids essential for health. EPA or eicosapentaenoic fatty acids can lower cholesterol and triglycerides and increase HDL, decreasing the risk of coronary artery disease and artery blockage. DHA or docosahexaenoic acid is a vital component of all cell membranes, especially brain cells and retina; it supports a healthy brain and learning ability.

The difference between cod liver oil and fish oil is that the former has a high level of vitamin A and D. EPA and DHA are precursors of lipid mediators that have anti-inflammatory properties which reduce inflammation in our body. They can relieve arthritis pain, anxiety, depression, and lower blood pressure and triglycerides. They also increase good cholesterol, prevent plaque buildup in arteries, and promote immune function and bone density.

If you prefer to take dietary supplements, choose either cod liver or fish oil, not both. Too much omega-3 intake may result in side effects. Cod liver oil is considered safe but may have side effects such as heartburn, belching, nosebleeds, and making the blood hard to clot. It is not advisable to take cod liver oil supplements during pregnancy because of their high vitamin A content, which could harm the fetus. Consult a doctor before taking any dietary supplement, particularly if you have a heart condition or fish and shellfish allergies.
