Summary
Brief summary
In this randomised, double-blind, placebo-controlled study, 100 young-to-middle-aged adults aged 18 to 45 years with self-reported sleep difficulties will be randomly assigned to receive magnesium L-threonate (Magtein) or a placebo for 6 weeks. Changes in cognitive performance will be assessed at baseline and week 6 by administering The National Institutes of Health (NIH) Toolbox Cognition Battery and Raven’s Progressive Matrices Second Edition (Raven’s 2). Moreover, self-report questionnaires will be administered to examine changes in sleep quality, restorative sleep, and general wellbeing. Changes in sleep patterns will also be monitored using an Oura Ring. Finally, to measure potential changes in gaming skills, the 3D Aim Trainer, a first-person shooting game, will be administered at baseline and week 6.
