Omega 3-6-9is well known product containing three different fatty acids. Omega 3 and Omega 6 are the polyunsaturated acids and Omega 9 is the monounsaturated fatty acid. Polyunsaturated fatty acids oxidises easily in the presence of heat or light. It reduces the cardiac problems as well as depression, arthritis, asthma problems too.
Working Principle Of Omega 3:
Omega 3 fatty acids DHA and EPA block inflammation pathways in the cell. They block multiple pathways. We know that the most common Omega 3 fatty acid is ALA (Alpha Linoleic Acid). In our body it converts to Stearidonic Acid (SDA), then Eicosatrienoic Acid(ETE), after that it changes to Eicosapentaenoic Acid (EPA) and at last, it will be docosahexaenoic acid (DHA). This one is consumed by our body. It reduces the heart problems.
Working Principle Of Omega 6:
Omega 6 fatty acids are largely produced for the purpose of promoting growth and at the time of inflammatory cascade Omega, 6 is converted to halt cell damage and promote cell repair. The most common Omega 6 fatty acid is Linoleic acid. In our body, it converts to Gamma Linoleic Acid ( GLA), after that it changes to DihomoGamma Linoleic Acid ( DGLA). Then it will be Arachidonic Acid (AA) and at last, it will be Docosatetraenoic Acid. This one is absorbed by our body. It reduces nerve pain.
Working Principle Of Omega 9:
The Omega 9 fatty acids are nonessential monounsaturated fatty acids because our body can make it. If we intake enough Omega 3 and Omega 6 in our diet then it is not necessary to take Omega 9 from outside. Omega 9 is produced enough in our body. Otherwise, we intake Omega 9 in our diet. The Omega 9 ETrA is present in normal and young tissues. The derived components from COX [17-19], LOX [20,21] and epoxygenase  can be metabolized potential signaling molecules. It may reduce the progression of adrenoleukodystrophy, a fatal disease that affects the brain and adrenal glands and it boosts up the memory.
If we choose a combined supplement and choose the best one with a high concentration of EPA and DHA.
