The Importance of Choosing a High-Quality Fish Oil Supplement

How to Choose the Right Fish Oil: A Guide to Picking a High-Quality Supplement


Fish oil supplements are a popular way to increase your intake of Omega-3 fatty acids, which are essential for supporting heart, brain, and joint health. With so many options on the market, however, it can be difficult to choose a high-quality fish oil supplement that will deliver the desired health benefits. In this guide, we'll explore the factors to consider when choosing a fish oil supplement and how to incorporate it into your diet.


Factors to Consider When Choosing a Fish Oil Supplement

Source of the fish oil

Omega-3 fatty acids are found in various parts of the world, as they are primarily sourced from fish and seafood. However, some regions are known to have a higher concentration of fish that are rich in omega-3s.

One such region is the cold waters of the North Atlantic, which is known for its abundance of fatty fish species such as salmon, mackerel, herring, and cod. These fish are commonly consumed in countries like Norway, Iceland, and Scotland, where seafood is a staple part of the diet.

The coastal regions of Peru and Chile in South America are also known for their high levels of omega-3-rich fish, particularly the Peruvian anchovy, which is a major source of fish oil and omega-3 supplements.

Overall, the availability and concentration of omega-3 fatty acids in fish may vary depending on the species, region, and other environmental factors, but fatty fish from cold waters tend to be the richest source.

Extraction Method

Triglyceride (TG) and ethyl ester (EE) are two different forms of omega-3 fatty acids that are commonly found in fish oil supplements.

TG form is the natural form of omega-3s found in fish and is considered to be the more stable and bioavailable form. This means that it is more easily absorbed and utilized by the body. TG form is obtained through the cold-pressed extraction method which preserves the natural state of the fatty acids, maintaining their molecular structure and improving their overall quality.

EE form, on the other hand, is a synthetic form of omega-3s that is produced through the process of molecular distillation. This form of omega-3s is less stable and less easily absorbed by the body. Additionally, the process of converting omega-3s into EE form can result in the loss of some of the natural nutrients found in fish oil. While EE form supplements are more commonly available on the market due to their lower cost, they may not provide the same health benefits as supplements in TG form.

Added Nutrients

Many high-quality fish oil supplements contain added nutrients such as Vitamin E and Lutein. These nutrients provide additional benefits to overall health and wellness, including reducing inflammation and oxidative stress. Lutein, in particular, supports eye health and can improve vision.


Ensuring that a fish oil supplement is pure is essential to avoid harmful contaminants such as heavy metals and toxins. It's crucial to choose supplements that have been tested for purity and quality by third-party testing organizations. This way, you can be confident that the supplement you are taking is safe and effective.

Dosage and Form                                               


Based on the dosage reference of the World Health Organization and the Food and Agriculture Organization of the United Nations, here are the recommended daily doses of fish oil for different age groups:

  • Children aged 3-6: 150-300 mg of EPA and DHA per day, which can be obtained from 0.5-1 teaspoon (2.5-5 ml) of fish oil

  • Children aged 6-12: 200-500 mg of EPA and DHA per day, which can be obtained from 1-2 teaspoons (5-10 ml) of fish oil

  • Teenagers aged 12-18: 500-1000 mg of EPA and DHA per day, which can be obtained from 2.5-5 teaspoons (12.5-25 ml) of fish oil

  • Adults aged 18 and above: 500-1000 mg of EPA and DHA per day, which can be obtained from 1-2 teaspoons (5-10 ml) of fish oil

It's important to note that pregnant women and breastfeeding women should consult with their healthcare provider before taking any supplements, as their recommended dosage may vary.


Liquid fish oil supplements are more easily absorbed, but may have a stronger taste and require refrigeration.

Softgel capsules are easier to swallow and don't require refrigeration, but may be less easily absorbed.

Gummies or chewable supplements may be a good option for those who have difficulty swallowing pills, but may contain added sugars and other ingredients that could impact their overall health.

Vegan or plant-based alternatives like algae oil supplements are available for those who prefer not to consume animal products, but may be more expensive and have a different nutrient profile.



Choosing a high-quality fish oil supplement can be a daunting task, but it's important for overall health and wellness. By considering factors such as the source of the fish oil, extraction method, added nutrients, purity, and dosage and form, you can select a supplement that meets your individual health needs. Remember to consult with a healthcare professional if you have any questions or concerns.
