The Claim
A single 0.2 g/kg dose of creatine improves cognitive performance in vegetarians during sleep deprivation, with specific enhancements in language processing speed and psychomotor vigilance, and this effect is attributed to baseline creatine deficiency increasing responsiveness to supplementation.
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.
Vegetarians who are sleep-deprived show better performance in tasks requiring quick thinking and reaction time after taking a single dose of creatine, likely because their usual diet leads to lower natural creatine levels.
See the scientific wording
Vegetarians show significant cognitive improvement from a single 0.2 g/kg creatine dose during sleep deprivation, particularly in language processing speed and psychomotor vigilance, suggesting baseline creatine deficiency enhances responsiveness to supplementation.
What the research says
1 studyStudy: Single-Dose Creatine Reduces Sleep Deprivation-Induced Deterioration in Cognitive Performance
Taking a small amount of creatine helped people stay sharper and react faster when they hadn’t slept, especially in tasks involving language and attention — suggesting it helps the brain when tired.
