The Claim
A dose-dependent cognitive benefit of creatine supplementation during sleep deprivation exists, with a 0.2 g/kg dose resulting in smaller improvements compared to a 0.35 g/kg dose, indicating a ceiling effect in brain creatine uptake under metabolic stress.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
During sleep deprivation, taking more creatine (0.35 g/kg) leads to slightly better cognitive performance than taking less (0.2 g/kg), but the benefit does not increase beyond a certain dose, suggesting the brain reaches a limit in how much creatine it can use under these conditions.
See the scientific wording
Creatine’s cognitive benefits during sleep deprivation are dose-dependent, with a 0.2 g/kg dose producing smaller improvements than a previously studied 0.35 g/kg dose, suggesting a ceiling effect in brain creatine uptake under metabolic stress.
What the research says
1 studyStudy: Single-Dose Creatine Reduces Sleep Deprivation-Induced Deterioration in Cognitive Performance
This study found that taking a smaller amount of creatine still helps your brain work better when you're sleep-deprived, but not as much as a bigger dose — which means more creatine gives you more brain help, up to a point.
