The Claim
A single 0.35 g/kg dose of creatine administered during sleep deprivation results in peak cognitive benefits approximately 4 hours post-ingestion, with effects persisting for up to 9 hours, indicating a delayed but sustained impact on brain energy metabolism and cognitive function.
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 0.35 grams of creatine per kilogram of body weight during sleep deprivation improves cognitive performance, with the strongest effects occurring about 4 hours after taking it and lasting up to 9 hours, likely due to sustained changes in how the brain uses energy.
See the scientific wording
The cognitive benefits of a single 0.35 g/kg creatine dose during sleep deprivation peak at approximately 4 hours post-ingestion and persist for up to 9 hours, suggesting a delayed but sustained effect on brain energy metabolism and cognitive function.
What the research says
1 studyThis study found that taking a single dose of creatine helps your brain work better even when you're sleep-deprived, and the good effects last for many hours — starting a bit later but sticking around.
