Citicoline enhances frontal lobe bioenergetics as measured by phosphorus magnetic resonance spectroscopy
Key Finding
Citicoline supplementation increases brain ATP levels and energy metabolism in the frontal cortex.
Plain-English Summary
This neuroimaging study used magnetic resonance spectroscopy to examine the effects of citicoline supplementation on brain bioenergetics in healthy adolescents. Participants received either 500mg or 1000mg of citicoline daily or placebo for 28 days.
Results demonstrated that citicoline supplementation increased brain ATP levels and phosphocreatine synthesis in the frontal cortex, indicating improved brain energy metabolism. These changes were dose-dependent, with the 1000mg dose producing more pronounced effects.
The frontal lobe is critical for executive functions including planning, attention, and working memory. Enhanced energy metabolism in this region could support improved cognitive performance. The study provides direct neurobiological evidence for citicoline's effects on brain function and suggests mechanisms underlying its cognitive benefits. Citicoline was well-tolerated at both dose levels.
