Through our common ownership interest with the large fishing company Bristol Bay Alaska Seafoods (BBAS), we know where our fish oil comes from and can guarantee our materials are sustainably sourced. Because our raw materials are processed at sea and the livers are flash frozen to -35°C aboard the ship, the oxidization process is put on pause within 20 minutes of the catch. This is the main reason our products are so fresh and contain naturally high levels of vitamins and omegas. Our processing facility is located within minutes of the vessel-offload zone in Dutch Harbor, Alaska, which decreases the transportation time of the raw material and allows for faster processing—resulting in a premium product.

Most fish oil products are highly refined and only deliver fatty acids extracted solely from a fish source, typically sardines. Our marine superfoods are derived from minimally processed, nutrient-dense seafood materials in order to preserve the natural nutrient profiles. They contain both complete profile omega-3 fatty acids and other valuable nutrients, including fat-soluble vitamins, natural carotenoids, and pro-resolving mediators.

Fish oil solely consists of the lipids native to the fish species from which the product was derived. When eating fresh, wild-caught fish, the body benefits from high-quality protein, minerals, vitamins, and factors such as iodine, as well as health-promoting fatty acids. But our minimally processed marine superfoods deliver an even more complete array of nutritional factors native to the wild-caught fish from which they are derived.

Steward Supplements’ objective is to produce a premium cod liver oil that is minimally processed and retains a high degree of naturally occurring vitamins. Our Alaskan cod naturally has low toxicant numbers, which allows us to use a lighter hand in our treatment process. Our oil is categorized as semi-refined, as we never exceed a heat level of 90°C in our treatment process. The only refining procedure our oil goes through is the distillation process, which removes small amounts of polychlorinated biphenyls (PCBs), making the oil California Prop-65 compliant. We test our fish oil before and after our proprietary manufacturing process, and there is little to no transformation of the nutrient profile.

Steward Supplements products are all manufactured, encapsulated, and bottled in the United States. Our oil is harvested at our Dutch Harbor, Alaska, facility and sent to Minnesota for molecular distillation, after which it’s sent to our bottling locations in either California or New Jersey for encapsulation and bottling. Both of these bottling locations (and each of our partner facilities) are MSC-certified and produce only premium-grade products—through every step of the process, we only work with like-minded companies who share our core values around sustainability, traceability, and quality.

No. Steward Supplements’ marine superfoods are tested for over 450 potential environmental toxins by the prestigious German testing laboratory Eurofins Labs. Steward’s proprietary production process gently cleans natural lipid complexes to ensure compliance with all national and international quality regulations. The Bering Sea is known to be one of the most pristine environments on the planet; therefore, our process only requires a very light touch that doesn’t alter the health-promoting, nature-formed nutrient profile.

All Steward Supplements products are free of mercury. Our raw materials are all sourced from the purest body of water in the Pacific: the Bering Sea.

We ensure all Steward Supplements products are tested for quality every step of the way. During each part of our treatment process, we send samples to a laboratory called Eurofins Labs that tests each product for over 450 types of contaminants. If you’re interested in seeing a certificate of analysis (COA), we’ve made them available for all of our products.

Most available fish oil products are highly refined in order to remove potential environmental toxins, leaving only the fatty acids. Steward Supplements harvests fish from the pristine Bering Sea and freezes the material used to make marine superfoods aboard the vessels soon after the catch. The combination of a clean ocean and flash freezing captures a pure raw material that requires very little processing. Minimal processing means our marine superfoods deliver combinations of nutrients that may more effectively promote optimal health and wellness than other fish oils.

The raw materials used in Steward Supplements products are sourced through a common ownership stake in Bristol Bay Alaska Seafoods (BBAS). We use sustainably caught cod livers in our cod liver oil, sourced from BBAS’s freezer-longline fishing fleet based out of Dutch Harbor, Alaska. The crew extracts the livers from the cod upon catch and immediately freezes them at temperatures below -35°C. Each one of these cod is caught by the hook and line method, which has minimal environmental impact on the seafloor and is sustainably certified by the Marine Stewardship Council (MSC). 

The raw materials for our salmon oil (typically the head of the salmon) are sourced from the Bristol Bay gillnet fleet, which is sustainably endorsed by the MSC. The process is like our cod liver oil process: BBAS’s processing vessels collect the salmon from the fishing boats for cleaning and freezing, then they offload the product at our facility in Dutch Harbor, Alaska.

The key to freshness is in the harvesting process. All the raw materials that go into our marine superfoods are line caught, immediately processed on board the fishing vessels, and then flash frozen to stop oxidation and enzymatic breakdown. The result is marine superfoods that are extremely fresh and will remain stable for up to 24 months. We also add small amounts of natural, soy-free antioxidant stabilizers to enhance and preserve freshness.
