Fatty acids are building blocks of fats that naturally occur in food. They are classified as saturated fatty acids, monounsaturated fatty acids (like omega-9), and polyunsaturated fatty acids (like omega-3 and omega-6). Each type of fatty acid has a unique chemical structure and can be found in different foods.

Omega-3 fatty acids are fats that naturally occur in oily fish, shellfish, and certain plants. In this product, they are derived from fish oil from anchovy and sardine.

Omega-3, -6, and -9 are three types of unsaturated fatty acids that differ in structure and origin: Omega-3 fatty acids are mainly found in oily fish, algae, and flaxseed. Well-known forms are EPA and DHA. Omega-6 fatty acids can be found in sunflower oil, corn oil, and nuts. Omega-9 fatty acids are monounsaturated fats commonly found in olive oil.

EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are two types of omega-3 fatty acids that often occur together in fish oil. They are widely used in supplements for children and adults.
