The Claim
A creatine dose of 0.2 g/kg during sleep deprivation produces modest cognitive protection that is less pronounced than the cognitive protection observed with a 0.35 g/kg dose, indicating a dose-dependent relationship between creatine intake and cognitive outcomes 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.
When people are sleep-deprived, taking 0.2 grams of creatine per kilogram of body weight provides a small improvement in cognitive performance, but taking 0.35 grams per kilogram provides a larger improvement.
See the scientific wording
The cognitive benefits of a 0.2 g/kg creatine dose during sleep deprivation are modest and less pronounced than those seen with a 0.35 g/kg dose, indicating a dose-dependent relationship between creatine intake and cognitive protection under metabolic stress.
When the brain is stressed from lack of sleep, it needs more energy to keep thinking clearly. Creatine from food or supplements enters brain cells and helps make more ATP, the molecule that powers brain activity. More creatine means more ATP is made, which keeps brain cells working properly during sleep deprivation, so thinking doesn't slow down as much.
What the research says
1 studyStudy: Single-Dose Creatine Reduces Sleep Deprivation-Induced Deterioration in Cognitive Performance
The study found that taking more creatine (0.35 g/kg) helps your brain work better when you're sleep-deprived than taking less (0.2 g/kg), so higher doses give more protection—even though the smaller dose still helps a little.
