One Creatine Dose Kept Sleep-Deprived Brains 12% Sharper A randomized, double-blind crossover trial kept 29 healthy adults awake for 21 hours straight ... half the time on a single moderate dose of creatine (~14g), half the time on placebo ... and found the creatine group held on to up to 12% more cognitive performance across logic, reaction time, and language processing. Host Dave Asprey breaks down why sleep deprivation is just another form of brain energy stress, how creatine's phosphate-buffering mechanism stabilizes ATP in the prefrontal cortex under pressure, and why this changes how he thinks about red-eye flights and all-nighters. Vegetarians and women showed the largest effects ... your baseline diet sets your ceiling. Sources: https://pubmed.ncbi.nlm.nih.gov/42075005/ https://www.nutraingredients.com/Article/2026/04/21/single-dose-creatine-may-support-cognition-in-sleep-deprivation-study/ https://pmc.ncbi.nlm.nih.gov/articles/PMC10902318/ https://medicalxpress.com/news/
