Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main aim of this randomized controlled trial is to evaluate cerebral blood oxygenation after 7-day administration of a creatine-guanidinoacetic acid (GAA) mixture in healthy adults before, during, and after a series of cognitive tests.
