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.

Cause and effect
1 study reviewed
In plain English

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 study
  1. Study: Single dose creatine improves cognitive performance and induces changes in cerebral high energy phosphates during sleep deprivation

    This 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.
