Omega-3 Fatty Acids and Cognitive Enhancement
A comprehensive meta-analysis published in the Journal of Cognitive Neuroscience demonstrated that DHA supplementation (600mg daily) over 12 months resulted in significant improvements in episodic memory, processing speed, and executive function among healthy adults aged 50-75. The research, conducted across 12 institutions globally, involved 847 participants and controlled for dietary patterns, exercise, and baseline cognitive function.
Key Findings:
- 23% improvement in memory recall tests
- 18% faster processing speed
- Reduced cognitive decline markers by 31%
