The role of fish oil: why omega-3 fatty acids are so important

Fish oil is a dietary supplement derived from the tissues of oily fish. It is known for its high content of omega-3 fatty acids, which play an important role in our health.

What are omega-3 fatty acids?

Omega-3 fatty acids are essential fatty acids that the body cannot produce itself. They must be ingested through food. The three most important omega-3 fatty acids are alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).

Why are omega-3 fatty acids important?

Omega-3 fatty acids play a crucial role in various aspects of our health. They are known for their anti-inflammatory properties, which can help prevent chronic inflammatory conditions.

In addition, omega-3 fatty acids are important for heart health and may reduce the risk of heart disease. They help lower cholesterol levels, regulate blood pressure and improve blood vessel function.

Omega-3 fatty acids are also essential for brain development and function. They support cognitive function and can reduce the risk of neurodegenerative diseases such as Alzheimer's.

Sources of omega-3 fatty acids

The best source of omega-3 fatty acids is oily fish such as salmon, tuna, mackerel and sardines. These types of fish contain high amounts of EPA and DHA.

Plant sources of omega-3 fatty acids are flaxseed, chia seeds and walnuts. These contain mainly ALA, which, however, can be converted into EPA and DHA in limited amounts in the body.

The importance of fish oil as a dietary supplement

For people who don't regularly eat oily fish or prefer plant-based sources of omega-3 fatty acids, taking fish oil capsules can be a useful supplement. Fish oil supplements contain concentrated amounts of EPA and DHA, allowing for easy and convenient absorption of these important fatty acids.


Omega-3 fatty acids, especially EPA and DHA from fish oil, play a vital role in health. They have anti-inflammatory properties, support heart health and are important for brain development and function. If you don't eat oily fish on a regular basis, taking a fish oil supplement can be a good option to ensure you're getting adequate amounts of omega-3 fatty acids.
