The specialized language of medicine, pharmacy or biochemistry provides categories of substances the name of which also contains the particle “essential” (for example: essential amino acids, essential fatty acids, etc.).

These are very important substances for the proper development and functioning of the human body, and the term “essential” means that although it needs them, the body cannot synthesize these molecules, so it must receive them from the outside, namely through daily food and food supplements.

There are several essential omega-3 fatty acids, of which docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are the most important and the most studied in the last 25 years.
