Krill Oil vs Fish Oil: Which is Better For Your Health?

Fish oil and krill oil have been a mainstay in the health and wellness conversation for years now for one primary reason: 

Omega-3 fatty acids. 

There’s a great reason for all the hype. 

Omega-3s have been clinically proven to deliver incredible health benefits such as: 

Heart health: Omega-3s have been clinically proven to support heart health in various ways.*1 

Eye health: Omega-3 is one of the structural components of the retina in the eyes, and supplementation can support overall eye health.*2 

Bone and joint health: Omega-3s can boost the amount of calcium in bones, which leads to improved bone strength.3 They are also beneficial in reducing joint discomfort and stiffness.* 

Mental health support: High levels of Omega-3s are associated with improved mood and cognitive function.*4 

Sleep quality: Omega-3 fatty acids, particularly DHA, may contribute to better sleep quality.*

So, if krill oil and fish oil have Omega-3s, you’ll get the same health benefits from either, right? 

Not exactly. 

It turns out there are several key differences between krill oil and fish oil—backed by science—that provide the answer to the question: 

Which is better for you: Krill or fish oil? 

When you look at the facts, there is really no comparison.

Here are four reasons krill oil is best for your health.

1. Omega-3 Health Benefits

Fish oil is renowned for its high concentration of Omega-3 fatty acids, specifically EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). As listed in the section above, these fats are crucial for providing many health benefits. 

Krill oil also contains EPA and DHA. However, unlike fish oil, the Omega-3s in krill oil are bound to phospholipids, which studies suggest may enhance the body’s absorption of these fatty acids.

Both supplements effectively deliver Omega-3 benefits, but krill oil may offer an edge in bioavailability.* This means that the same amount of Omega-3s might be more effectively used by the body when sourced from krill oil, potentially increasing its health benefits per gram.*

Advantage: Krill oil.

2. Additional Health Benefits

Beyond Omega-3s, only one type of oil has additional advantages. 

Fish oil is a well-established supplement often used for various conditions linked to Omega-3 deficiencies, but the benefits it provides are all related to Omega-3s. 

Krill oil, on the other hand, contains astaxanthin, a potent antioxidant that fish oil lacks. Astaxanthin offers additional antioxidant properties, protecting cells from damage and supporting your health.*

The astaxanthin in krill oil provides a unique bonus outside Omega-3s, offering more comprehensive health benefits.*

Advantage: Krill oil.

3. Absorption

The form of Omega-3s plays a crucial role in how well they are absorbed and utilized by the body. 

Fish oil’s Omega-3s are primarily in triglyceride form, which can be less efficiently absorbed compared to the phospholipid form found in krill oil. 

Phospholipids align more closely with the human body’s cell structure, facilitating a more straightforward absorption pathway. 

This enhanced absorption means that krill oil might offer more Omega-3 benefits at lower dosages, making it an appealing option for those who prefer to take fewer supplements.*

Advantage: Krill oil.

4. Purity and Sourcing

Purity is a significant concern when it comes to fish oil—and fish in general—as fish from the ocean can contain mercury and other environmental toxins. The purity of fish largely depends on the fish source, the food chain from which it comes, and the waters from which it is harvested. 

Fish oil is primarily derived from capelin, sand eel, anchovy, horse mackerel, cod liver, pilchard, and menhaden. These fish can be caught in many places worldwide, often in polluted oceans. 

In contrast, krill oil typically shows lower levels of contaminants for a few reasons: 

• Krill have short lifespans, giving them less time to ingest toxins

• Krill are on the bottom of the food chain, giving them less chance to ingest toxins

• Krill live in the Antarctic Ocean, which contains the most pristine waters on Earth

Note: Both krill and fish oil products should be certified by third-party organizations to ensure they are free from harmful levels of contaminants and that they contain the advertised levels of Omega-3s.

Advantage: Krill oil. 

Both krill oil and fish oil offer valuable health benefits, particularly in delivering Omega-3 fatty acids essential for maintaining various aspects of health.*

However, krill oil has a clear advantage due to better absorption, lack of harmful contaminants, and additional antioxidant benefits from astaxanthin.*
