DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid) are both long-chain fatty acids from the omega-3 family that occur naturally in oily fish.

Triglyceride form (rTG) refers to the natural molecular structure in which omega-3 fatty acids are found in fish. In this form, the fatty acids are bound to a glycerol molecule, similar to how they are present in food.

The best-known omega-3 fatty acids are ALA (alpha-linolenic acid), EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). ALA is mainly found in plant oils such as flaxseed oil, while EPA and DHA are mainly present in oily fish and fish oil.

Fatty acids are divided into saturated and unsaturated fatty acids. Saturated fatty acids have no double bonds in their chemical structure and are mainly found in animal products such as butter, cheese and meat, but also in coconut oil and palm oil. Unsaturated fatty acids contain one or more double bonds and are mainly found in vegetable oils, nuts, seeds and oily fish.

Omega-3, 6 and 9 are types of unsaturated fatty acids. The difference lies in the position of the first double bond in the carbon chain. Omega-3 fatty acids, such as ALA, EPA and DHA, are found in oily fish, algae and certain plant oils. Omega-6 fatty acids can be found in sunflower oil, corn oil, soybean oil and nuts. Omega-9 fatty acids, such as oleic acid, are mainly found in olive oil, avocado and almonds.

The difference lies in the chemical structure. Saturated fatty acids have only single bonds between carbon atoms, while unsaturated fatty acids contain one or more double bonds. This structure influences, among other things, whether a fat is solid or liquid at room temperature.

Omega-3 fatty acids are naturally oily. A softgel capsule is suitable for liquid ingredients such as fish oil and protects the oil well from air and light. This helps preserve quality and flavor. Additionally, softgels are easy to swallow and contain the oil in liquid form, similar to how fats are consumed through food.
