Before the twentieth century, lipids were considered harmful to the body because of the cardiovascular risk associated with hyperlipidemia, in other words, excess lipids in the blood. However, as a result of their work and research, scientists have made a distinction between saturated fatty acids, i.e. "bad fats", and unsaturated fatty acids, i.e. "good fats".

Nowadays, we all know that the body needs "good fats" to function properly. These "good fats" are actually the omega-3 fatty acids, alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These fats are an essential source of energy for the body to help maintain cardiovascular and mental health. 

The sources of omega 3 fatty acids are of animal and vegetable origin, they are found in different types of fish, shellfish, krill, but also in walnuts, flax seeds or chia seeds. ALA, vegetable omega-3 fatty acids, found in walnuts or flax seeds, are not easily assimilated by the body. EPA and DHA, marine omega 3 fatty acids, present in different types of fish and shellfish, are very easily assimilated by the body. 

For a long time we have been eating fish to assimilate omega 3 fatty acids. However, the quantity of omega 3 fatty acids present in the body after eating fish is not sufficient. In addition, over the last twenty years, the level of mercury in the ocean has increased by 30%. Fish assimilate omega 3, but also pollutants. A large consumption of fish and shellfish can therefore be harmful to health and this contributes to overfishing. 

"I gave up fishing the day I realized that when I caught
I gave up fishing the day I realized that when I caught them, the fish weren't wriggling with joy."

Louis de Funès

To overcome these problems, the idea came to create food supplements rich in omega 3. However, it was necessary to discover where the omega 3s assimilated by fish and shellfish came from. The fish fed on euphausiids, which themselves fed on micro-algae. These are a very rich source of omega 3. Microalgae convert the sun's energy into omega 3, in other words, they practice photosynthesis. Algae cultivated in compliance with the specifications of good practices are the "cleanest" source of marine omega 3 that exists. To obtain a sufficient quantity to meet the nutritional needs of humans, researchers have developed the concentrated form of all microalgae, the precious algal oil.
