Algae could replace fish oil as the future of omega-3 for pets

The pet nutrition industry is preparing for major changes in omega-3 sourcing, with algae set to replace fish oil as a sustainable alternative. Julian Pietrzyk, Ph.D., technical product manager at MiAlgae Ltd., will highlight these shifts at Forum Europe 2026 in Nuremberg. His session will explore the differences between omega-3 types and their impact on pet health.

Pietrzyk's presentation, titled 'Perceptions, sources and the evolving role of long-chain omega-3s in pet nutrition', will address how EPA and DHA directly benefit pets. These fatty acids support inflammation control, skin health, joint mobility, brain function, and heart health. In contrast, ALA—found in plant sources—requires inefficient conversion in cats and dogs, making it less effective.

Current fish oil ingredients often raise quality concerns, with ALA dominating omega-3 profiles instead of the more beneficial EPA and DHA. Algae-derived omega-3s, however, provide the same advantages without the environmental, ethical, or contamination issues linked to marine sources. MiAlgae's own product, made using whisky by-products, guarantees high DHA concentrations sustainably.

The market for algae-based omega-3s in animal nutrition is expanding rapidly. By the end of 2026, it is expected to reach around $500 million globally. Major companies like DSM (through its Veramaris joint venture), Corbion (AlmegaPL), and Norsk Algatec are leading the shift. DSM's high-DHA algae strains, for example, are already reducing dependence on wild fish stocks.

Forum Europe 2026, co-located with Interzoo, will take place on May 11 in Nuremberg. Pietrzyk's insights come as the industry seeks more reliable and eco-friendly omega-3 solutions for pet food.

The move toward algae-based omega-3s reflects growing demand for sustainable pet nutrition. Pietrzyk's session will outline how these alternatives match fish oil's benefits while avoiding its drawbacks. With the market projected to expand significantly, algae could soon become the standard in pet food formulation.
