Assessing the Quality of Blackmores Fish Oil

When evaluating a fish oil supplement, several factors determine its overall quality. These include the origin of the fish, the purity of the oil, the concentration of active omega-3s (EPA and DHA), and evidence of third-party testing. Blackmores addresses each of these points with its robust manufacturing and testing standards.

Sourcing and Sustainability

Blackmores sources its fish oil from 100% wild-caught small fish, such as anchovies and sardines, primarily from Peru. This choice of small fish is a deliberate strategy to reduce the risk of high-level contamination from heavy metals like mercury, which bioaccumulate in larger fish. The oil extraction process is often completed within 24 hours of the fish docking to ensure maximum freshness and potency. Furthermore, Blackmores asserts that its supply chain is responsible, which aligns with modern sustainable fishing practices.

Purity and Contaminant Testing

A critical aspect of fish oil quality is purity, ensuring the oil is free from harmful toxins. Blackmores performs extensive testing on its fish oil for a range of contaminants.

Heavy Metals: Rigorous testing is performed for mercury.
Environmental Pollutants: The oil is tested for PCBs (polychlorinated biphenyls) and dioxins.
Oxidation: Processes are in place to minimize oxidation, a primary cause of rancidity and the unpleasant "fishy" burps. Being a member of GOED (the Global Organization for EPA and DHA Omega-3s) means Blackmores adheres to strict industry standards for product quality and freshness.

Omega-3 Concentration Levels

The concentration of EPA and DHA per capsule is a key quality indicator, as it determines the potency and efficacy of the supplement. Blackmores offers a range of products with varying strengths, which means the level of quality in terms of potency depends on the specific product. For example:

Standard Fish Oil 1000: Provides 300 mg of omega-3s per capsule.
Omega Daily: Offers a more concentrated dose with 600 mg of omega-3s per capsule.
Omega Triple Super Strength: This product is highly concentrated, delivering 900 mg of omega-3s per capsule.

IFOS Certification: The Quality Gold Standard

While Blackmores conducts its own extensive testing, independent third-party certification provides an unbiased assurance of quality. The International Fish Oil Standards (IFOS) program is one of the most respected third-party testing bodies for fish oil. It tests products for potency, freshness, and purity. As of June 2024, at least one of Blackmores' products, the Omega Ultra Fish Oil, is IFOS certified. This certification provides strong evidence of the brand's commitment to high quality for specific products.
