Alpha Linolenic Acid(ALA) can be seen mainly in some of the plant oils such as the oil from flaxseed, soybean and canola oils. Eicosa Pentadienoic Acid(EPA) and Docasa Hexanoic Acid(DHA) are the omega fatty acids which can be seen in sea foods.Such as fish and other e.t.c.Alpha Lenolenic Acid(ALA) is one of the important omega fatty acids which the body can’t produce by itself.  We have to provide them for our body by consuming foods with Alpha Linolenic Acid plant oils or drinking beverages which are in high amount of Alpha Linolenic Acid omega 3 fatty acids.

Though our body cant produce Alpha Linolenic Acid, but it have the capability to convert the Alpha Linolenic Acid (which is produced in our body after the consumption of foods) to Eicosa Pentadienoic Acid and thereby to Docasa Hexanoic Acid. But these covert ion process only provides small amount of Eicosa Pentaecosa Acid and Docasa Hexanoic Acid to our body. So, in order to increase the quantity of omega in our body, we should must eat foods with high amount of Alpha Linolenic Acid, Eicosa Pentadienoic Acid and Docasa Hexanoic Acid.


Omega 3 is the most essential elements of our membranes, which are surrounded to each and every cell of our body. Retina in the eye, brain and spinal cells are mostly consisted with high amount of Docasa Hexanoic Acid. And most of the functions of our body parts such as heart, lungs,blood vessels, immune system and endocrine system (which is also known as the network of hormone production glands) are consisted with the high calories energy provided through omega.
