    Effect of creatine supplementation on body composition and performance: a meta-analysis

    Branch JD

    Published in International Journal of Sport Nutrition and Exercise Metabolism

    Methodology

    Meta-analysis of 100 randomized studies examining creatine supplementation effects on lean body mass and exercise performance across exercise modes and durations.

    Key Findings

    Creatine produced a significant positive effect size for lean body mass and for performance in short-duration, high-intensity tasks, with negligible effect for tasks lasting more than 150 seconds.

    Conclusions

    Creatine supplementation reliably improves lean mass and high-intensity, short-duration performance.

    Limitations

    Older analysis with heterogeneous protocols; few female or older-adult participants; publication bias possible.

    Supplements Studied

    Creatine produced a significant positive effect size for lean body mass and short-duration, high-intensity performance.

    Outcomes Measured

    Creatine produced a significant positive effect size for lean body mass and short-duration, high-intensity performance.
