Antarctic Krill Oil for Cats and Dogs

Krill oil is one of the most bioavailable sources of omega-3 fatty acids. Unlike traditional fish oils, the EPA and DHA in krill oil are bound to phospholipids, which means your pet’s body can absorb and use them more efficiently.

These essential fatty acids support:
• Healthy skin and coat
• Joint mobility and comfort
• Heart health
• Brain and cognitive function
• Kidney and immune health

Because of this enhanced absorption, pets often need less krill oil to see noticeable benefits.

Most fish oils contain omega-3s in triglyceride form, while krill oil delivers them in phospholipid form – the same structure found in your pet’s cell membranes.

That means:
• Better absorption
• Better delivery into cells
• Less waste

Krill oil also naturally contains astaxanthin, a powerful antioxidant that helps protect the oil from oxidation and supports your pet’s health at the cellular level.

Some pet parents notice improvements in skin, coat, and energy within a few days to weeks. For deeper support – like joints, heart, or cognitive function – consistent daily use over 4 to 8 weeks typically provides the best results.

As with any nutritional support, consistency matters.

Yes. Our krill oil is sourced from the pristine waters of the Antarctic and undergoes strict quality and purity testing.

It is:
• Free from heavy metals and common ocean contaminants
• Naturally stabilized with antioxidants (no synthetic preservatives needed)
• Carefully handled to maintain freshness and potency

We prioritize purity at every step – from ocean to bottle.

Omega-3 oils are delicate and can oxidize when exposed to air, heat, or light.

That’s why we use:
• High-quality glass bottles (not plastic) to reduce potential toxin exposure
• Naturally occurring astaxanthin to protect the oil
• Careful production and handling practices to maintain freshness

This helps ensure your pet is getting a fresh, effective product – not degraded oil.

This is one of the most important questions to us – and we’re glad you asked.

Krill harvesting in the Antarctic is one of the most tightly regulated fisheries in the world. It is managed under strict international guidelines designed to protect the entire ecosystem.

Key points:
• Less than 1% of the total krill biomass is harvested annually
• Large buffer zones protect feeding areas for whales, seals, and penguins
• Continuous monitoring ensures long-term sustainability

Our source uses a modern mid-water harvesting technique designed to minimize environmental impact and maximize traceability and catch accuracy. Scientific studies estimate bycatch at just 0.2–0.3%, among the lowest of any fishery globally.

Marine Stewardship Council (MSC) certified:

MSC is an international non-profit organization that recognizes and rewards efforts to protect ocean ecosystems and ensure sustainable seafood supplies AQC holds MSC certification for the Antarctic krill fishery.

Sustainable Fisheries Partnership (SFP) certified:

SFP is a global nonprofit working to promote sustainability and transparency in seafood supply chains. For six consecutive years, the Antarctic krill fishery received an “A” rating from SFP for biomass health, the only reduction fishery globally to achieve this rating.

In its 2025 global review of over 2,500 marine fishery resources, the most comprehensive assessment of its kind, the FAO classified the Antarctic krill fishery as sustainably fished, crediting the strict management framework governing the fishery.

When sourced responsibly, krill oil can be one of the most sustainable marine omega-3 options available.

Our krill is wild-caught from the Antarctic Ocean – one of the cleanest marine environments on Earth.

We work with a responsible krill fishery that follows strict sustainability standards to ensure both purity and environmental protection.

Not all omega-3s are created equal.

The source impacts:
• Absorption in the body
• Risk of contaminants
• Stability of the oil
• Overall effectiveness

Krill oil’s unique structure and clean sourcing make it one of the most efficient and trusted omega-3 options for pets.

Yes! This formula is safe and beneficial for both cats and dogs when used as directed.

Because it is a pure oil (not a capsule), it can be easily added to your pet’s food for daily support.

The overwhelming majority of pets do not get enough biologically available omega-3s from their food alone.

Even when omega-3s are listed on pet food labels, they are often:
• Degraded during processing
• Present in insufficient amounts
• Not in a highly absorbable form

Supplementing helps ensure your pet is getting the support their body needs.

Yes, omega-3 fatty acids are essential for skin health.

They help:
• Reduce dryness and flakiness
• Support a healthy skin barrier
• Improve coat softness and shine

Many pet parents notice visible improvements in coat quality within days to weeks.

Yes. Omega-3 fatty acids are essential nutrients, meaning your pet’s body needs them regularly.

When used as directed, krill oil is safe for daily, long-term use and provides ongoing support for overall health.

Store in a cool, dry place away from direct sunlight. Because we use protective packaging and natural antioxidants, refrigeration is not required – but it is always safe if you prefer.

Omega-3 oils are extremely delicate, and plastic containers can create several problems over time. Not only is plastic permeable to oxygen, which can cause oils to oxidize and go rancid faster, but certain plastics may also leach unwanted compounds into the oil itself.

We wanted to avoid exposing your pet’s omega-3 supplement to:

• Excess oxygen
• Microplastics
• BPA/BPS compounds
• PFAS and other chemical contaminants often associated with plastics

It may seem like a small detail, but for a sensitive oil like omega-3s, the container truly matters.

That rich color comes from astaxanthin – a natural antioxidant found in krill.

It helps:
• Protect the oil from oxidation
• Support cellular health
• Add an extra layer of nutritional benefit

Our Antarctic Krill Oil has a shelf life of at least 18 months when stored properly in a cool, dry place away from direct sunlight.

Because omega-3 oils are naturally delicate, we took extra care with our packaging choices to help protect freshness and stability. The combination of:

• Glass packaging instead of plastic
• An air-limiting closure system
• Naturally occurring astaxanthin antioxidants

helps maintain the quality and integrity of the oil over time.

For best freshness, we recommend using the product consistently once opened and storing it with the lid securely closed between uses.

Not all omega-3s are structured the same – and the form they are delivered in can affect how well your pet’s body absorbs and uses them.

There are three common forms of omega-3s found in supplements:

1. Ethyl Ester (EE) → A processed form often used in concentrated fish oils. This form does not naturally occur in fish and must be converted by the body before it can be fully utilized.
2. Triglycerides (TG) → The natural fat form found in most fish oils and whole fish. This form is generally better absorbed than ethyl esters.
3. Phospholipids (PL) → The form found in krill oil. Phospholipids are a major component of cell membranes, making them especially compatible with how the body transports and utilizes omega-3s.

Why does this matter?

• Phospholipid omega-3s help:
• Absorb more efficiently
• Travel more easily through the bloodstream
• Deliver EPA and DHA directly into cells
• Provide more benefits with smaller serving sizes

Krill oil also naturally contains astaxanthin, an antioxidant that helps protect the delicate oils from oxidation.

In simple terms:

• Ethyl esters are highly processed.
• Triglycerides are natural.
• Phospholipids are natural and highly bioavailable.

Krill oil is very safe for both cats and dogs when used as directed. Because it is a rich source of omega-3 fatty acids, some pets may experience mild digestive upset if too much is introduced too quickly.

Possible temporary side effects can include:
• Loose stool
• Softer stool
• Mild stomach upset

Starting with a smaller amount and gradually increasing to the recommended serving can help sensitive pets adjust comfortably.

If your pet has a bleeding disorder, is taking blood-thinning medications, or has a medical condition requiring dietary restrictions, it is always best to consult your veterinarian before starting any new supplement.

As with any marine-based ingredient, discontinue use if your pet shows signs of sensitivity or intolerance.

Krill are small crustaceans, not fish, so some pets with fish sensitivities may tolerate krill oil differently than traditional fish oil products.

Veterinary science and immunology show that a pet with a finned fish allergy can safely consume pure krill oil. They belong to completely different biological categories.

That said, every pet is unique. If your cat or dog has a known seafood allergy or history of food sensitivities, we recommend introducing any new supplement slowly and monitoring closely for signs of intolerance.

Yes! One of the unique benefits of krill oil is that it naturally contains astaxanthin, a powerful antioxidant found in Antarctic krill.

Astaxanthin helps:
• Protect the delicate omega-3 oils from oxidation
• Support cellular health
• Help combat oxidative stress in the body

This natural antioxidant is one reason krill oil is often considered more stable than many traditional fish oils.

The deep reddish color of krill oil comes naturally from astaxanthin, with no artificial colors or additives needed.
