    Published in Experimental Gerontology

    Methodology

    Meta-analysis of randomized controlled trials of creatine supplementation on memory, attention and processing speed in healthy adults.

    Key Findings

    Creatine improved short-term memory and reasoning, with the largest effects under sleep deprivation or metabolic stress; effects on learning speed in rested young adults were small.

    Conclusions

    Creatine gives context-dependent cognitive benefits, strongest when brain energy supply is stressed.

    Limitations

    Few trials; cognitive test batteries differ widely.

    Supplements Studied

    Creatine improved short-term memory and reasoning, with the largest effects under sleep deprivation or metabolic stress

    Outcomes Measured

    Creatine improved short-term memory and reasoning, with the largest effects under sleep deprivation or metabolic stress

    Creatine improved short-term memory and some reasoning tasks but showed no consistent benefit for reaction time or executive function
