Flaxseed Oil vs Fish Oil: The Great Debate

There has been an ongoing debate among health experts and consumers today when it comes to the best source of omega 3; it’s called flaxseed oil vs fish oil. This article hopes to help you in determining how each one functions and how each one can actually contribute to one’s health, whether positively or negatively.

Where They Are the Same

Before we get into the versus thing, let us know first how they are similar from each other. For one, they contain omega 3 fatty acids, though in different forms. For flaxseed, it’s called ALA. For fish oil, there are two. They are known to be DHA and EPA. Interestingly, ALA is considered to be the parent chain since it can be converted into EPA and DHA.

They are also available in almost the same forms. These two supplements can be purchased in terms of pills or gels or capsules. The choice will be dependent to you.

Flax oil vs Fish Oil: The Differences

However it’s pretty obvious there are there are more differences than similarities. Let’s begin with the source. Fish oil facts suggest that you can get the oil from different types of fish, such as mackerel, sardines, anchovies, and salmon. You can also get it from cod fish; thus, you have the cod liver fish oil.

However, when it comes to flaxseed oil, there’s only one source, and that is from the flax plant.

Fish oil capsules benefits are almost similar to those of flaxseed oil. Both are known to take care of the heart, especially when it comes to lowering the blood pressure and cholesterol. However, since fish oil contains more DHA than flaxseed, it is more ideal for proper brain development and the prevention of mood and brain disorders such as Alzheimer’s disease and depression.

The body doesn’t produce DHA and EPA. This is the reason why we do need to take omega-3 fatty acids from outside sources. Since you’re directly getting these from fish oil your body doesn’t have to do a lot of processes. You can immediately make full use of these components.

As mentioned, when you take flax oil, ALA has to be broken down into two components, and usually, you will have more of EPA than DHA even if you need more of the latter than the former.


However, when it comes to safety issues, you will feel safer with flaxseed. This is because there’s such a thing called fish oil toxicity. If you have chosen the wrong type of fish oil supplementation, there’s a huge tendency that the supplement you have still contains traces of heavy metals such as lead and mercury. These are currently polluting the waters and are unfortunately ingested by the fish.

Flaxseed oil contains another omega fatty acids called omega 6, which is another component the body requires. However, if you have more of it, you will also be more prone to developing inflammation.

In the flaxseed oil vs fish oil argument, it’s becoming quite clear that both are almost on the same foot. Both are needed and when used wisely can be excellent for the betterment of one’s health.
