Omega-3 fatty acids are part of the polyunsaturated fatty acids. Unlike saturated fatty acids, the body cannot produce them by itself. They must therefore be provided by the diet. Since Omega-3 fatty acids are vital for our body, they are called essential fatty acids.
There are several types of Omega-3 fatty acids. They differ mainly in their chemical structure and natural origin.
The most important Omega-3 fatty acids are:
- Eicosapentaenoic acid (EPA)
- Docosahexaenoic acid (DHA)
- Alpha-linolenic acid (ALA)
