certificates of analysis
Our oils and products are regularly tested by laboratories. This is particularly important to us in order to maintain the high quality standard of our products. We would like to give you the opportunity to view these laboratory analyses. Below you will find the various certificates.

Analysis of additional ingredients
Our excipients are natural and are also needed as antioxidants.
Raw material analyses
Not only are our products analyzed, but also our raw materials. Here you can find, for example, the
TOTOX (freshness value) as well as the
EPA and DHA content of our fish oils and algae oil.

Information on the TOTOX value
What is the TOTOX value?
The TOTOX value (Total Oxidation Value), also known as the “freshness value ,” provides an overall assessment of the oxidation level of oils, including fish and algae oils. When an oil is exposed to oxygen, the fatty acids oxidize – the oil becomes rancid and develops an unpleasant taste and smell. Our nose and sense of taste are therefore already good “measuring instruments” for assessing the freshness of an oil. Additionally, there are methods for evaluating the freshness of omega-3 products. The TOTOX value is frequently used as a measure of freshness in these cases. Depending on the raw material, the value varies within a natural range. For example, cod liver oil naturally has a slightly lower TOTOX value than fish oil from small, fatty fish. According to GOED (Global Organization for EPA and DHA Omega-3s), TOTOX values below 26 are considered safe for consumption.
TOTOX value in NORSAN products
In the production of our Omega-3 oils and capsules, we adhere to very strict standards regarding purity, freshness, and quality. Following production, the TOTOX values of our raw materials are tested in every batch. Furthermore, we have the TOTOX values of our finished products regularly verified by an independent laboratory.

What influences the TOTOX value?
Omega-3 oils are similar to other high-quality oils used in cooking: they are sensitive to light and heat. Storage is therefore an important factor that can affect freshness and thus the TOTOX value. These factors influence the TOTOX value:
- Temperature
- Light
- Oxygen
- Other added ingredients
To provide you with the highest quality and freshness of Omega-3 oils, we have strict standards for the storage of our Omega-3 products after production. When you order directly from our website, we can therefore guarantee that freshness is ensured through proper storage and delivery of the most recent batch.
