Why Omega-3 is so important for your health

Omega-3 fatty acids are essential fats that our bodies cannot produce themselves. It is therefore important to consume them regularly through food or through dietary supplements.

What is Omega-3 and why do we need it?

Omega-3 fatty acids play a critical role in cellular function, heart health, brain and vision (1) . These polyunsaturated fatty acids may reduce the risk of chronic diseases such as heart disease, cancer, and arthritis (2) .

Difference between animal sources and vegan sources

Traditional sources of omega-3 usually come from fatty fish such as salmon, mackerel and sardines. Vegan sources, on the other hand, are plant-based and come from foods such as algae, hemp, walnuts and flaxseed (3) .

The importance of EPA and DHA

EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are two of the most important omega-3 fatty acids and have specific roles in the body:

  • EPA (eicosapentaenoic acid): This fatty acid has anti-inflammatory properties and can therefore be helpful in treating conditions such as arthritis. It has also been shown to play a role in regulating mood disorders, particularly depression.

  • DHA (docosahexaenoic acid): DHA is a major component of the cell membranes in the brain and eyes and plays a critical role in the development and function of these organs. DHA deficiency during pregnancy and breastfeeding can have adverse effects on brain and eye development in the fetus or infant. (4.5)

The optimal ratio of EPA to DHA

The ideal ratio of EPA to DHA can vary depending on your health goals. Some experts recommend a 2:1 ratio (EPA:DHA) for general health purposes, while other studies suggest a 1:1 ratio for optimal heart health. However, it is important to emphasize that individual needs and ideal dosage may depend on various factors, including age, gender, health status and dietary habits. A consultation with a nutritionist or doctor is advisable to determine your personal needs.

Benefits of vegan omega-3

  • Environmentally friendly: The production of plant sources of omega-3 has a smaller ecological footprint compared to fishing.
  • Free from contaminants: Vegan sources often have less risk of containing contaminants such as mercury, which can be found in some types of fish. (6)
  • Sustainable: Unlike overfishing, plant-based sources offer a sustainable option.

What do you have to pay attention to with vegan omega-3 supplements?

When purchasing vegan omega-3 supplements, it is important to ensure there are sufficient amounts of EPA and DHA. It is also advisable to choose a product that has been tested for purity and quality.
While the "best" supplements can be subjective and depend on individual needs, algae oil capsules are one of the preferred options for vegan DHA. For ALA, flaxseed oil or chia oil capsules can be considered.


Omega-3 fatty acids are essential for health. While traditional sources come from fish, vegan sources such as seaweed offer a sustainable and environmentally friendly alternative. When choosing a dietary supplement, it is important to pay attention to quality and purity.

If you regularly take various medications, you should consult your doctor before taking omega-3 capsules. This is particularly relevant for people taking blood-thinning medications (anticoagulants). Omega-3 fatty acids can inhibit the aggregation of blood platelets and thus increase the tendency to bleed. In such cases, an adjustment of the medication dose or combination may be necessary. It is therefore essential to seek medical advice in advance.
