Krill: The Hero Ingredient in Pet Food

Blog overview

Just as humans take supplements to compensate for what their bodies lack, our furry friends also require nutritional supplements. While pets cannot naturally produce sufficient omega-3s in their bodies, these essential fatty acids play a vital role in their overall health. Fortunately, there is a hero ingredient that can fulfill this nutritional need—Antarctic krill.

Antarctic krill, a species with one of the largest total biomasses in the world, has gained popularity in pet food, supplements, and treats due to being such a great source of omega-3s. 

These tiny crustaceans inhabit the unpolluted waters of Antarctica, making them free of environmental toxins and contaminants. So, let's explore a few significant aspects that make krill so essential for pet nutrition.


Marine-sourced omega-3s: The best choice for pets

Research has shown that marine-sourced omega-3s are the most beneficial for pets. Unlike plant-based sources, pets are unable to convert enough plant-sourced omega-3s into their bodies. The most efficient form of omega-3s for pets is those bound to phospholipids, which are found in krill.


Phospholipids are natural and integral parts of pet cells that maintain the strength, flexibility, and integrity of cells and cell membranes. They are 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.

By incorporating omega-3s from krill into their diets, pets can benefit from these essential nutrients in a highly effective and bioavailable form.

Superior and sustainable: A win-win for pets and the planet

While the health benefits of krill are undeniable, we also recognize the importance of sustainability. Krill is considered one of the most sustainable sources of marine omega-3s. At QRILL Pet, all our products have received the Marine Stewardship Council (MSC) certification, the highest-ranking sustainability certificate available.
