The UK fish oil market is currently in a phase of sustained expansion primarily due to the rising number of applications in nutraceuticals, pharmaceuticals, animal feed, and aquaculture.
Fish oil is the most known source of omega-3 fatty acids (EPA and DHA) and are proven to have health-promoting effects, which include the ability to support cardiovascular health, improve cognitive function, and possess anti-inflammatory properties. The popularity and consumers' demand for high-quality, purified salmon oil that is scientifically proven to provide health benefits are quite growing these days.
Top players such as DSM, Croda International, Pelagia, GC Rieber, and BASF are dominating the UK fish oil market by investing in cutting-edge purification technologies alongside ensuring sustainability fish oil sourcing and product formulations.
The recently increased interest in plant-based and algae-derived omega-3 alternatives is another factor that collaboratively supports the development of the industry through the expansion of companies' product lines to meet the needs of vegetarian and vegan customers.
The UK Food Standards Agency (FSA) and the European Food Safety Authority (EFSA) have taken steps to ensure sustainability and traceability. They have mandated the mercury-free processing and eco-friendly sourcing of fish oil products.
The UK government's strong focus on marine sustainability is motivating the responsible management of fisheries and generating transparency in the fish oil production process.
The sector is sustaining its growth despite some hurdles that include changes in raw material prices, competition from other omega-3 suppliers, and very strict government rules because consumers are becoming more and more conscious of health issues, there are more product innovations, and fish oils are now included in a wider range of functional foods, dietary supplements, and pharmaceuticals.

Increased Requirement for Fish Oil with Formulation-Grades
The UK market has seen the rise in demand for highly purified, pharmaceutical-grade fish oil due to its clinically proven value in handling cardiovascular diseases, inflammation, and neurological conditions.
Manufacturers are concentrating on the purification of by-products routes which involve molecular distillation and supercritical fluid extraction to assure their products are free from contamination and to have higher strength formulations. Regulatory authorities are also stimulating Clinical trials along with evidence-based justifications that have led to fish oils being included in some drugs and therapies.
Sustainable Sourcing and Ethical Marine Stewardship
The lack of knowledge about the rapid changes of overfishing and marine ecology makes the UK fish oil industry put an emphasis on sourcing responsibly and good fisheries management.
Manufacturers get certifications from bodies like the Marine Stewardship Council (MSC) and Friends of the Sea (FOS) that ensure the fish oil is from non-endangered fish species and also benefits in by-product application. Furthermore, companies are instigating the use of by-catch technology and close-loop processing systems that will act in a better way for the environment.
Encapsulation and Delivery Systems: The Technology of Tomorrow
The innovations that were made in the delivery and encapsulation of fish oil have gone far in introducing the supply of these products in a more efficient way. Employed technologies include liposomal encapsulation, microencapsulation, and soft gel techniques; they have been utilized to prevent oxidation as well as accelerate the absorption rate of omega-3 fatty acids. This innovation is most valuable in functional foods and medical-grade fish oil supplements applications, where stability and efficacy are very important.
% share of Individual categories by Process and End User in 2025
As refined fish oil is subjected to thorough purification and thus heavy metals, contaminants, and oxidation by-products are removed, it constitutes 55% of the UK market.
