Cod liver oils and fish oils are both supplements rich in omega 3 fatty acids, which are highly beneficial to our bodies. Despite their similarities, both supplements aren’t the same. They come from different sources, have slightly different benefits, and present different risks. So, which is best for you? If you want more information to guide your decision, then read on.
Cod Liver Oils VS Fish Oil: The Difference
One of the main differences between cod liver oil and fish oil is their source. While cod liver oil capsules come specifically from the codfishes’ liver, fish oil is simply an oil extract of the flesh of fishes like herring, anchovies, tuna, salmon, mackerel, etc. The percentage of fatty acid in both oils are different. Arctic cod liver oil has approximately 9% EPA/14% DHA, while fish oil has 18% EPA/12% DHA. Therefore, fish oil technically has double the amount of EPA in cod liver oil but a 2% difference in DHA. There’s more; cod liver oil naturally contains vitamin D and A, making it an excellent choice over fish oils for those living in climates with relatively low sunlight exposure.
