Research Summary
Uridine has shown promise in animal studies for enhancing cognitive performance and neuroplasticity, with mechanisms involving membrane phosphatidylcholine synthesis and dendritic growth. Human clinical trials remain limited, though small studies suggest cognitive benefits, particularly in combination with choline and docosahexaenoic acid. Further rigorous research is needed to establish optimal dosing and long-term safety in healthy populations.
