Creatine Boosts Brain Function at 10-25 Grams, Easing 21 Hours of Sleep Loss

Summary
Experts say creatine’s cognitive benefits are strongest when the brain is energy-stressed, with studies showing better processing speed and working memory during sleep deprivation, stress and fatigue.
A 2024 University of Pennsylvania study found supplements can raise brain creatine, though doctors said healthy, rested adults often see mixed or minimal gains because brain levels are tightly regulated.
Clinical trials cited by specialists used 10 to 25 grams daily—well above the standard 5-gram muscle dose—with high-dose use generally limited to four to eight weeks or taken as a single 20-25 gram dose for acute sleep loss.
Research reviews from 2018, 2023 and 2024 also linked creatine to modest improvements in short-term memory, reasoning, focus and possible benefits for depression, anxiety and concussion recovery.
Creatine remains one of the safest studied supplements, experts said, with bloating or gastrointestinal discomfort the main side effects and added caution for people with kidney disease.
