Understanding Kirkland Signature's Manufacturing Process
Costco is renowned for its Kirkland Signature private-label products, which are famous for their high quality and competitive pricing. However, this brand is not a single manufacturing entity but a curated collection of products made by various partner companies. When it comes to supplements like krill oil, Costco contracts with specialized manufacturers who must adhere to stringent quality and purity standards. This strategy allows Costco to offer premium goods while controlling costs by leveraging the expertise of established producers. Many Kirkland Signature supplements are even verified by the United States Pharmacopeia (USP), an independent, non-profit organization that sets strict standards for product integrity and manufacturing practices.
The Likely Manufacturer: Aker BioMarine
While Costco does not publicize its specific manufacturing partners for competitive reasons, industry analysis and product research strongly suggest that Aker BioMarine, a Norwegian company, is the primary supplier for Kirkland Signature krill oil. Aker BioMarine is a global leader in the krill oil market and the producer of the Superba™ Krill oil brand, known for its high-quality ingredients and sustainable practices.
Here are several factors supporting this conclusion:
- Industry Leadership: Aker BioMarine controls the entire supply chain, from sustainable krill harvesting in Antarctic waters to processing at its facilities in Houston.
- Sustainable Sourcing: The Kirkland Signature krill oil product description explicitly mentions it is sourced from 100% Antarctic krill, aligning perfectly with Aker BioMarine's origin story. Aker BioMarine is certified by the Marine Stewardship Council (MSC) for its responsible harvesting.
- Ingredient Traceability: Aker BioMarine promotes a fully traceable supply chain, from 'catch to capsule,' a premium feature often associated with high-end private labels like Kirkland Signature.
- Proprietary Technology: Aker BioMarine uses advanced technology, such as its Flexitech™ process, to produce krill oil concentrates rich in omega-3s, phospholipids, and astaxanthin. This matches the key selling points advertised for the Kirkland Signature product.
The Journey from Antarctic Waters to Your Bottle
Krill oil production is a multi-step process that ensures a high-quality final product. It begins with the sustainable harvesting of tiny shrimp-like crustaceans called krill from the cold, pristine waters of the Antarctic.
- Harvesting: Using specialized vessels, krill are captured and immediately processed onboard to maintain freshness and nutrient integrity. This on-vessel processing is a hallmark of premium suppliers like Aker BioMarine.
- Extraction: The krill meal is subjected to an extraction process, often using an organic solvent or supercritical CO2, to separate the oil. The goal is to maximize the yield of active ingredients like EPA, DHA, and astaxanthin.
- Refinement: The extracted krill oil is then refined to remove impurities and concentrate the beneficial compounds. Aker BioMarine's proprietary technology, Flexitech™, is used to create highly concentrated forms of their krill oil.
- Encapsulation: The finished krill oil is encapsulated into softgels, which are then packaged and shipped to distribution centers, including Costco.
Why Choose Krill Oil Over Fish Oil?
Krill oil has gained popularity as an alternative to traditional fish oil. While both provide beneficial omega-3 fatty acids EPA and DHA, there are key differences that make krill oil a preferable choice for many consumers.

Krill Oil vs. Fish Oil Comparison
| Feature | Kirkland Signature Krill Oil (Likely via Aker BioMarine) | Typical Fish Oil | Source | Krill, a tiny crustacean from Antarctica | Oily fish like sardines, mackerel, and anchovies | Omega-3 Form | Phospholipids, which are easier for the body to absorb | Triglycerides, which require more processing by the body | Antioxidants | Naturally contains Astaxanthin, which gives it its red color | Lacks Astaxanthin unless added artificially | Potential Side Effects | Smaller, easier-to-swallow capsules; less likely to cause a 'fishy burp' | Larger capsules and a greater risk of a fishy aftertaste | Sustainability | Sourced from the abundant Antarctic krill population and often MSC certified | Sustainability varies widely depending on the fish species and fishing practices | Price | Generally more expensive due to complex sourcing and processing | Typically more affordable and widely available | Traceability | Often fully traceable from 'catch to capsule' | Varies by brand; traceability may not be as comprehensive | Health Benefits | Supports heart, brain, joint, and liver health | Also supports heart, brain, and joint health; benefits are well-researched |
Conclusion
While the Kirkland Signature label is prominently displayed, the actual producers of Costco's krill oil are third-party manufacturers, with strong evidence pointing to Aker BioMarine as the primary supplier. By partnering with a leading industry player known for its sustainable Antarctic sourcing and advanced processing technologies, Costco ensures its customers receive a high-quality product that stands up to national brands. This manufacturing strategy, combined with the independent verification from organizations like USP, provides confidence in the product's purity and potency. The phospholipid advantage and astaxanthin content make Kirkland Signature krill oil a unique and beneficial alternative to traditional fish oil for those seeking enhanced omega-3 absorption and other health benefits.
