Omega-3 Fatty Acids: EPA and DHA in Neuroinflammation

Key Mechanisms

• Direct Anti-Inflammatory Action: EPA (Eicosapentaenoic Acid) and DHA (Docosahexaenoic Acid) decrease the production of pro-inflammatory cytokines and eicosanoids in the central nervous system.
• Resolvins and Protectins: Both fatty acids serve as precursors for specialized pro-resolving mediators (SPMs), which actively resolve neuroinflammation rather than just suppressing it.
• Cell Membrane Fluidity: DHA is a critical structural component of neuronal cell membranes, enhancing receptor function and cellular communication while reducing oxidative stress.

Nutritional Considerations

• Imbalance with Omega-6: Modern diets often feature an excessive ratio of omega-6 to omega-3 fats, which promotes a pro-inflammatory state detrimental to neurological health.
• Ratio and Purity: Achieving an optimal balance requires high-purity marine sources, ensuring adequate intake of both EPA and DHA while avoiding heavy metal contamination.
• Synergistic Nutrients: The efficacy of omega-3 fatty acids in modulating inflammation is often supported by adequate levels of antioxidants and other essential co-factors to prevent lipid peroxidation.
