The Claim
A single oral dose of 0.35 g/kg creatine monohydrate administered during 21 hours of sleep deprivation in healthy young adults improves cognitive processing speed in language, logic, and numeric tasks by 16–24%, reduces fatigue scores by 8%, stabilizes cerebral phosphocreatine-to-inorganic phosphate ratios, and prevents acidification of brain tissue.
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 a specific dose of creatine monohydrate by mouth during a night of little sleep may help maintain faster thinking in language, logic, and math tasks, reduce feelings of tiredness, and help preserve normal energy-related chemistry in the brain.
See the scientific wording
A single oral dose of 0.35 g/kg creatine monohydrate during 21 hours of sleep deprivation in healthy young adults improves cognitive processing speed in language, logic, and numeric tasks by 16–24% and reduces fatigue scores by 8%, while stabilizing cerebral phosphocreatine-to-inorganic phosphate ratios and preventing acidification of brain tissue, suggesting acute creatine supplementation can partially counteract metabolic and cognitive decline induced by sleep loss.
What the research says
1 studyThis study found that taking a big one-time dose of creatine helped people stay sharper and less tired after staying up all night, and it also helped their brain maintain its energy balance — just like the claim said.
