The Claim
A single oral dose of 0.2 g/kg creatine monohydrate reduces the deterioration in cognitive performance during 21 hours of sleep deprivation in healthy young adults, with improvements of up to 12% in logic, numerical ability, language processing speed, and psychomotor vigilance.
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.
Taking 0.2 grams of creatine monohydrate per kilogram of body weight as a single oral dose can reduce the decline in cognitive functions such as logical reasoning, numerical processing, language speed, and attention during 21 hours without sleep in healthy young adults.
See the scientific wording
A single oral dose of 0.2 g/kg creatine monohydrate reduces the deterioration in cognitive performance during 21 hours of sleep deprivation in healthy young adults, with improvements of up to 12% in logic, numerical ability, language processing speed, and psychomotor vigilance, suggesting creatine may support brain energy metabolism under acute 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 single dose of creatine helped people stay sharper and react faster during a long night without sleep, improving their thinking skills by up to 12%. So yes, creatine can help your brain work better when you're tired.
