Fatty acids are the building blocks of fats and occur naturally in foods such as oil, nuts, fish and seeds. They are divided into saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids.

Omega 3 is a group of polyunsaturated fatty acids. The best-known forms are EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). These are mainly found in fish oil, shellfish, crustaceans, and certain algae.

Omega 3 mainly comes from fish and algae and contains EPA and DHA. Omega 6 is mainly found in vegetable oils such as sunflower oil and corn oil. Omega 9 is found in products such as olive oil and avocado, and mainly consists of oleic acid. The difference lies in the chemical structure and the food sources in which they are found.

The softgel capsules are made from plant-based gelatin, but the omega 3 extract is derived from fish. As a result, the capsules are not suitable for vegans or vegetarians who do not consume fish products.

Fish oil is obtained from fish, while algae oil comes from microalgae. Both can contain EPA and DHA, but algae oil is plant-based in origin and is often used in vegan supplements.
