The Claim
Sleep deprivation for 21 hours in healthy young adults reduces cerebral phosphocreatine-to-inorganic phosphate (PCr/Pi) ratios by approximately 4.7% and lowers brain pH by 0.03 units, and a single 0.35 g/kg creatine dose partially prevents these changes.
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.
After 21 hours without sleep, healthy young adults show a small decrease in brain energy reserves and a slight drop in brain pH, suggesting increased energy use and acid buildup; taking creatine before sleep deprivation partially reduces these changes.
See the scientific wording
Sleep deprivation for 21 hours in healthy young adults reduces cerebral phosphocreatine-to-inorganic phosphate (PCr/Pi) ratios by approximately 4.7% and lowers brain pH by 0.03 units, indicating increased energy demand and cytosolic acidification, which are partially prevented by a single 0.35 g/kg creatine dose.
What the research says
1 studyWhen people stay awake for 21 hours, their brain runs low on energy and gets more acidic, but taking a big dose of creatine helps slow down those changes and keeps the brain working better.
