Physiologically, both EPA and DHA act as critical competitive substrates for cyclooxygenase (COX) and lipoxygenase (LOX) enzymes. By outcompeting pro-inflammatory arachidonic acid (an Omega-6) for these enzymes, they drastically downregulate the systemic production of inflammatory eicosanoids (prostaglandins and leukotrienes)17. Crucially, they serve as the direct biological precursors for a highly specialized class of immune-resolving autacoids known as Specialized Pro-resolving Mediators (SPMs)—which include resolvins, protectins, and maresins17. Unlike traditional anti-inflammatory pharmaceutical drugs (like NSAIDs) that merely block the initiation pathways of inflammation, SPMs actively orchestrate the actual resolution phase of the inflammatory response17. They achieve this by directly stimulating macrophage phagocytosis to clear out cellular debris, severely lowering serum triglyceride concentrations in the liver, reducing all-cause cardiovascular mortality risk by upwards of 21 percent, and restoring total tissue homeostasis following acute metabolic, physical, or immune stress17.
