Fatty acids are the building blocks of fats. They are found in food and are categorized as saturated, monounsaturated, and polyunsaturated fatty acids. Each type has a different chemical structure and is found in various food sources.

Saturated fatty acids have a straight structure without double bonds and are common in animal fats such as butter and cheese. Unsaturated fatty acids have one (monounsaturated) or multiple (polyunsaturated) double bonds and are mainly found in plant oils, nuts, seeds, and fish.

Omega-3 fatty acids are polyunsaturated fatty acids. They are divided into different types, including ALA (from plant sources) and the well-known EPA and DHA (mainly from fish oil).

EPA stands for eicosapentaenoic acid. It is a polyunsaturated omega-3 fatty acid naturally found in oily fish and fish oil.

DHA means docosahexaenoic acid. This is also a polyunsaturated omega-3 fatty acid found in fish, shellfish, and crustaceans, and in fish oil supplements.

EPA and DHA are both omega-3 fatty acids, but they differ in structure and length. DHA has more double bonds than EPA and is often found in higher concentrations in certain types of fish and algae. In supplements, they are often offered together.
