In adults aged 50–65, consuming more fish before starting omega-3 supplements does not change how much the supplements affect inflammation-related molecules in the blood, even though those who ate...
Mechanism
Synthesis from 1 study
Taking omega-3 supplements puts the right building blocks into your cells, and when there's inflammation, your body turns those building blocks into molecules that help stop the inflammation. This process works the same way whether you ate a lot of fish before or not, which is why the supplements...
Most probable mechanism
When people take omega-3 supplements, the body absorbs the fatty acids and puts them into cell membranes. When inflammation happens, these fatty acids are pulled out and turned into special molecules that help calm down inflammation by cleaning up cellular waste and reducing signals that cause swelling and pain.
Dietary EPA and DHA from supplementation are absorbed into the bloodstream and incorporated into phospholipid membranes of immune and endothelial cells
Upon inflammatory activation, phospholipase enzymes release EPA and DHA from membrane phospholipids
EPA and DHA are metabolized by lipoxygenase and cyclooxygenase enzymes into specialized pro-resolving mediators such as Resolvin D1 and Resolvin D4
Specialized pro-resolving mediators bind to G-protein-coupled receptors on immune cells, triggering signaling that promotes phagocytosis of apoptotic cells and reduces production of pro-inflammatory eicosanoids such as PGD2, 5-HETE, and 12-HETE
