Omega-3 fats from fish oil calm brain inflammation and change brain immune cells into a less irritated state.
See the scientific wording
Long-chain omega-3 fatty acids, specifically docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), reduce neuroinflammation and promote a shift in microglial cells toward an anti-inflammatory phenotype.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Systematic Review and Meta-Analysis of Omega-3 Fatty Acid Supplementation on Neuroinflammation and Microglial Phenotype
Search randomized controlled trials and cohort studies assessing omega-3 intake and brain inflammation markers (e.g., cytokines, PET imaging of microglial activation) and pool effect sizes.
Double-Blind Placebo-Controlled RCT of Omega-3 Fatty Acid Supplementation on Neuroinflammation
Randomize adults with mild cognitive impairment or at risk for neuroinflammation to receive omega-3 (DHA+EPA) or placebo for 6-12 months; measure CSF or serum inflammatory markers and brain PET imaging of microglial activation (e.g., TSPO binding).
Prospective Cohort Study of Dietary Omega-3 Intake and Incidence of Neuroinflammatory Disorders
Follow healthy adults over 10+ years, assess omega-3 intake via food frequency questionnaires, and track development of neurodegenerative or psychiatric disorders associated with neuroinflammation.
Preclinical Study of Omega-3 Supplementation on Microglial Phenotype in a Mouse Model of Neuroinflammation
Use a mouse model of neuroinflammation (e.g., LPS-induced or aging), feed omega-3 enriched diet, and measure microglial markers (IBA1, CD68, CD206) and cytokine profiles in brain tissue.
