NORSAN fish oil
100% natural fish oil from wild catch
The sourcing for our NORSAN fish oil is meticulously selected based on the following core criteria:
- Fishing method, sustainability and fishing area
- Extraction and purification of the fish oil
- Particularly advantageous analytical parameters such as TOTOX value, heavy metals and PCBs
Our team combines more than 30 years of industry experience, which we use to manufacture the best products. Our sourcing process begins with the selection of fish catches and suppliers that meet our rigorous safety standards and guarantee full transparency across the entire supply chain.
The NORSAN fish oil can be considered the best omega-3 oil for therapeutic purposes:
- High proportion of omega-3 fatty acids (up to 35%)
- A particularly high proportion of omega-3 EPA and a ratio of at least 2:1 compared to omega-3 DHA
In order to guarantee the high requirements in terms of quality and properties of our NORSAN fish oil, we pay attention to high standards when catching the fish, which are checked and certified by independent organizations such as IFOS (5 star rating) and Friend of the Sea. The oil stems from wild-catch of small fish such as mackerel, anchovies and sardines.

Natürliches Fischöl aus Wildfang
“Die beste Nahrung ist so natürlich wie möglich”. Geleitet von diesem Grundsatz verwenden wir immer – und ohne Ausnahme – den natürlichen Fischölkomplex aus dem Fisch und niemals chemisch veränderte Fischölkonzentrate. Dieser natürliche Fischölkomplex enthält einen hohen Anteil von bis zu 35 % der wertvollen Omega-3-Fettsäuren.
Ein natürliches Fischöl wie NORSAN Fischöl enthält ein breites Spektrum von bis zu 50 unterschiedlichen Fettsäuren. In einem konzentrierten Fischöl-Produkt ist diese natürliche Zusammensetzung zerstört und stattdessen erhält man konzentrierte Mengen an ausgewählten Fettsäuren. Es ist noch wenig bekannt, wie sich das (bearbeitete) konzentrierte Öl nach dem Konsum im Körper verhält. Um ähnlich gute Effekte wie beim Konsum von fettem Fisch zu erreichen, werden natürliche, nicht konzentrierte Produkte empfohlen.

Sustainability and quality
NORSAN fish oil is FOS certified and is obtained from fish that all come from waters that are certified by FOS as sustainable. FOS criteria include that:
- Oils stem from fish stocks that are not overfished.
- Prevention of fishing practices involving the by-catch of endangered species.
- Reduction of fishing practices that have an negative impact on the ecosystem.
- The fishery and oil extraction is energy efficient.
- Practices include high standards of social responsibility.
We appreciate the fact that we can harvest the high-quality raw materials from the sea. And we are aware of our responsibility towards the sea in this role. That is why we consider sustainability and the preservation of fish stocks to be the top criteria when selecting the oil. We work according to strict ethical and formal rules.
Gewinnung und Reinigung
The raw oil is obtained by gently heating and pressing the fish. The application of heat is unfortunately inevitable in this step. Nevertheless, in combination with vacuum pressure, the fatty acids are preserved in their natural form.
An oxygen-free processing environment is guaranteed for NORSAN fish oil, so that our oil is optimally protected against oxidation. Oxidation causes a fishy odor and has an unpleasant effect on the taste. The TOTOX value – the oxidation value or “freshness” value of the oil (the lower, the fresher) – is mostly is in the low ranger of 10 to 13, confirms the freshness of the oil.
As the marine habitat is unfortunately increasingly being contaminated by heavy metals and chemicals, its inhabitants also take in these pollutants through their diet. For this reason, it is necessary to carefully cleanse the raw fish oil and remove any potential harmful substances.
For this purpose, we use a modern facility in Norway, which in a unique way ensures the filtration and purification of heavy metals, pollutants and PCBs from the oil and at the same time maintains the qualities of the fish oil. The special refining process relies on effective and unique 3-fold cleaning during the first 3 process steps.
While the usual procedures in the industry only rely on a rough cleaning in 2 steps, we also carry out a special micro-distillation in which remaining pollutants are precisely filtered out.

The effect of omega-3 fatty acids on our health
Omega-3 EPA fatty acids are of central importance in controlling inflammatory processes in the body.
- Omega-3 EPA fatty acids are the starting point for the anti-inflammatory hormone prostaglandins type 3 (PGE3). As an eicosanoid, this hormone is the antagonist of the inflammatory hormone prostaglandin type 2 (PGE2), of which the omega-6 fatty acid (arachidonic acid) is the starting material. In this way, EPA curbs the pro-inflammatory effects of PGE2 from arachidonic acid. Side note: Aspirin also attacks the symptoms of PGE2.
- EPA can be converted into DHA. This fatty acid also has anti-inflammatory functions.
- A high proportion of omega-3 EPA in the body slows down the conversion capacity for the omega-6 fatty acids (omega-3 and omega-6 share the conversion capacity in the body). This indirect effect thus inhibits the formation of the omega-6 arachidonic acid in the body.
The ratio of EPA to DHA in Omega-3 Total is approximately 2: 1. This has proven to be effective in balancing an omega-6/3 imbalance in the body (based on more than 3.000 individual fatty acid analyzes in Germany).
