The Importance of Quality Fish Oil & How to Find It

Posted by EyePromise on Apr 17th 2025

Fish oil and Omega-3s are critical to a healthy body and healthy life. However, quality is more critical than most other ingredients when it comes to the benefits of fish oil.

What Quality Fish Oil Can Do

High-quality fish oil and Omega-3s have many benefits for the body. When the right quantities are ingested every day, they can help soothe eye irritation and dryness, relieve contact lens discomfort, and promote healthy tear function. Additionally, Omega-3s support the health of your:

  • Brain
  • Heart
  • Bones
  • Joints

What Poor Quality Fish Oil Can Do

Believe it or not, poor quality fish oil can actually irritate versus soothe, leading to issues throughout the same systems fish oil is supposed to help. This can lead to symptoms like:

  • Bloating
  • Heartburn
  • Weight gain
  • Risk of excess bleeding
  • Increased cholesterol

Poor quality fish oil can also contain contaminants like lead, mercury, and polychlorinated biphenyls (PCBs), a set of synthetic chemicals once found in industrial uses. Heavy metal poisoning or developmental and neurological problems are possible from ingesting too much of these over time, especially for kids.

How to Tell the Difference

For fish oil supplements, it’s best to choose a reputable brand that prioritizes quality ingredients and third-party testing for purity and safety. From there, it’s about checking the product itself for:

  • Total Omegas vs. fish oil: some products have tons of fish oil but very little Omega-3 fatty acids, which are the most beneficial ingredients in fish oil. A high-quality fish oil will have over 50% Omegas, so checking the supplement fact panel and doing a little bit of math is a good place to start.
  • EPA/DHA: the ratio of the two important Omega-3s is critical to the benefits they provide. For example, if you’re looking for relief from eye dryness or irritation or want to promote a healthy tear film, you should look for a 3:1 ratio of EPA to DHA.
  • Form of Omega-3: Some over-the-counter supplements go through processing which makes them less absorbable by the body. Re-esterified triglyceride (rTG) Omega-3 products help to boost absorption and let your body use the nutrients easier.
