The Positive Effects of Creatine on Sleep-Deprivation

Creatine, a popular dietary supplement commonly associated with strength training, also offers significant benefits for cognitive and psychomotor performance in sleep-deprived individuals. This post explores how creatine supplementation can help mitigate the negative impacts of sleep deprivation.

Enhancing Cognitive and Psychomotor Performance

Creatine supplementation has been found to support cognitive functions and mood in sleep-deprived individuals. A study conducted by McMorris et al. (2006) observed that subjects who took creatine showed significantly less decline in random movement generation, choice reaction time, balance, and mood state after 24 hours of sleep deprivation compared to those who took a placebo Effect of creatine supplementation and sleep deprivation, with mild exercise, on cognitive and psychomotor performance, mood state, and plasma concentrations of catecholamines and cortisol.

Improving Physical Performance and Skill Execution

Creatine also helps maintain physical performance and skill execution in sleep-deprived states. In a study involving elite rugby players, Cook et al. (2011) found that creatine supplementation helped maintain the accuracy of rugby passing skills during sleep deprivation, unlike placebo treatments which resulted in a significant drop in performance Skill execution and sleep deprivation: effects of acute caffeine or creatine supplementation - a randomized placebo-controlled trial.

Supporting Brain Energy Metabolism

Research also suggests that creatine supplementation can influence brain energy metabolism, which is crucial for coping with sleep deprivation. The supplement has been shown to buffer declines in the synthesis of ATP, providing energy reserves during periods of reduced sleep, which can help maintain cognitive functions Creatine supplementation, sleep deprivation, cortisol, melatonin and behavior.


Creatine is more than just a muscle-building aid. Its ability to enhance cognitive and physical performance in sleep-deprived individuals makes it a valuable supplement for those needing to maintain high levels of performance despite inadequate rest. Whether for athletes facing rigorous competition schedules or professionals needing to ensure peak cognitive function, creatine offers a scientifically supported advantage.
