Why Is Krill Such A Popular Ingredient For Pet Food?

Blog overview

Just as humans take supplements to compensate for what their body lacks, the same applies to pets. For example, pets can’t naturally produce sufficient omega-3s in their bodies, and so they need a nutritional supplement.

We all know that omega-3 fatty acids are important nutrients for pets and humans, being beneficial for brain development and heart health, among others.

And that’s where the Antarctic krill comes into play. It has become such an increasingly popular option in pet food, supplements and treats because it's a natural source of omega-3s.

What are the most important omega-3 ingredients for pet food?


This is the Antarctic krill

Krill are crustaceans that are low on the food chain. Now, you can find the Antarctic Krill, a species with one of the largest total biomasses in the world, in the Southern Ocean. These tiny crustaceans inhabit the unpolluted waters of Antarctica, which makes them free of environmental toxins and contaminants.

Here are 3 things you should know about krill


Marine-sourced omega-3

Studies have shown that marine-sourced omega-3s remain the most beneficial for pets. Why? Pets are unable to convert enough of the plant-sourced ones into their bodies. And the most efficient omega-3s are those bound to phospholipids, such as those found in krill.

Phospholipids are these natural and integral parts of pet cells that maintain the strength, flexibility, and integrity of cells and cell membranes. These are also responsible for carrying long-chain omega-3s EPA and DHA into pets' cell membranes, which is crucial for obtaining the health effects of omega-3s.

Scientifically proven benefits

We have already published several studies that prove and document the health benefits and efficiency of krill (and QRILL Pet). 

These studies proved that phospholipid omega-3s and other key nutrients found in QRILL Pet, such as choline, have positive effects on vital organs, and are essential for dogs having a healthy and happy life.

And we are not stopping here, as we are committed to keeping on documenting the effects of krill on pets' diets through more studies. 

Here’s a quick look into our recent studies that prove omega-3s and choline have positive effects on vital organs such as the heart, liver, kidney, brain, eyes, joints, muscles, skin and coat.





Superior and sustainable

While we know the health benefits of krill are endless, we also believe it’s important to have a healthy planet. And krill is considered one of the most sustainable sources of marine omega-3s. 

All of our QRILL Pet products have the Marine Stewardship Council (MSC) certification, which is the highest-ranking sustainability certificate available.

More than that, the Antarctic Krill Fishery has received an ‘A’ rating from the Sustainable Fisheries Partnership for the past 7 years.

One ingredient, many benefits

QRILL Pet is not only rich in omega-3s and choline but also offers some other important nutrients, such as astaxanthin, a powerful antioxidant that supports immune function and protects all body cells from oxidative stress. Marine proteins are other important nutrients found in krill that are highly palatable and digestible.

In order for pet food brands to stand out in a very competitive market, they need ingredients that are sustainable and nutritious, while also being palatable. And QRILL Pet (and krill) is that super-premium ingredient.
