Fatty acids are building blocks of fats and oils. They are found in food and supplements, and can be divided into saturated and unsaturated fatty acids. Most fats we eat contain a combination of both types.

Saturated fatty acids have a straight structure and are mainly found in animal fats such as butter or meat fat. Unsaturated fatty acids have one or more double bonds in their structure and are often found in vegetable oils and fish oil. Omega 3 fatty acids are part of the polyunsaturated fatty acids group.

Molecular distillation is a purification method where the oil is processed in a controlled way to remove unwanted substances. This refers to the production process, not to the composition of the fatty acids themselves.

Omega 3 is a group of fatty acids found in certain plants and fatty fish. Well-known forms are ALA (from plant sources such as flaxseed), and EPA and DHA, which are naturally present in fish oil. In this supplement, it specifically concerns EPA and DHA.

EPA stands for eicosapentaenoic acid and DHA for docosahexaenoic acid. Both are fatty acids that belong to the omega 3 group. They have different lengths and structures. EPA contains 20 carbon atoms, while DHA contains 22.
