5 Best Omega 3 Supplements for Eye Health | What Is the Best Fish Oil?

January 24, 20238 min read

Have you ever stood in the supplement aisle of the grocery store, so confused on which supplement to choose? We know the feeling. More specifically, the search for the right omega 3 fish oil supplement can be overwhelming. We’re here to help!

Omega 3 fatty acids are essential for healthy eyes. In the video below, we'll discuss how increasing your intake of omega-3s can help alleviate symptoms of dry eye. We'll provide tips on how to incorporate more omega-3 rich foods into your diet, as well as the benefits they bring. Tune in to learn more about the power of omega-3s and how they can help improve your eye health!


What is Fish Oil?

Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are the most common forms of omega 3 fatty acids. These healthy, polyunsaturated fats are often sought out for their antioxidant properties, and studies have shown benefits of supplementation throughout the body.

EPA is generally thought to play a larger antiinflammatory role, and DHA is often discussed in relation to brain and eye health. However, they always work together for the amazing benefits they provide.

The Types of Fish Oil for Eye Health

Ethyl Ester Oil

This form of fish oil is created by concentrating and then removing impurities from natural fish oils through a process that changes the molecular structure of the substance. It is never converted back into the more bioavailable form, which is triglyceride. 

While the ethyl ester form contains fewer contaminants and has higher levels of DHA and EPA when compared to the natural form, it is not as easily absorbed by the body. This reduced rate of absorption is most likely due to the fact that the structure of the oil must be broken down within the body and converted to triglyceride before it can properly be absorbed. 

This means you may have to up your dosage to notice the effects, or you may not notice any changes. The majority of fish oil supplements you’ll find on supermarket shelves are going to be ethyl ester based because they are much cheaper for companies to produce.

Re-Esterified Triglyceride Oil

This form of fish oil is the closest to eating real fish and is formed by extracting the natural oils from fatty fish. In order for the natural fish oil in your supplements to be pure enough for you to consume, it must undergo a purification process. Then, in order to be more bioavailable and easily absorbed by your body, the fish oil is reconverted back into the triglyceride form. Ethyl esters are never converted back into the triglyceride form. 

The greatest benefit of re-esterified triglyceride fish oil is its bioavailability. The critical fatty acids, EPA and DHA, are more easily absorbed by the body when compared to the ethyl ester form. 

Aside from more optimal absorption rates, the triglyceride form has fewer side effects. With ethyl esters, there is the possibility of digestive upset and fishy burps. However, if you consume only pharmaceutical grade triglyceride fish oil, this is not something you’ll have to worry about.
