One of the essential functions of Omega-3 is to help cell tissues to carry various substances – that are absorbed, and filtered in the cells – to the places where they are needed most.
Omega-3s within theses tissues act as a gatekeeper of the cells, by letting desired substances enter and keeping undesirable substances out. Because Omega-3 and Omega-6 compete to synthesize in cell tissues or phospholipids, Omega-3-containing tissues can work to prevent the unwanted and potentially life-threatening inflammatory effects of Omega-6.
