A systematic review and meta-analysis of the omega-3 fatty acids effects on brain-derived neurotrophic factor (BDNF)
Nutritional neuroscience (2024) · Meta analysis · n=587
The present systematic review and meta-analysis indicate the efficacy of omega-3 FAs in increasing the serum concentration of BDNF.
Based on 8-week RCT showing dose-dependent increases of 22%, 51%, and 142% at 100, 300, and 1000mg respectively. Individual response varies significantly (30% show variable response). NR-SAFE trial confirmed safety up to 2000mg.
Based on multiple meta-analyses showing EPA-dominant formulas >1g/day most effective. Effects plateau around 2-2.5g. Adjunctive use with antidepressants shows better outcomes than monotherapy.
