However, the influence of prior training experience on supplementation efficacy remains unknown.  \nObjective: This systematic review and dose–response meta-analysis of controlled trials evaluated the effects of Cr supplementation combined with RT on body composition, with particular emphasis on the differences between trained (experienced) and untrained (novice) individuals.  \nMethods: A systematic search of major databases was conducted to identify controlled trials published until March 2025. The effects of Cr supplementation on body mass, body mass index (BMI), FFM, fat mass (FM), and body fat percentage (BFP) were examined using random-effects meta-analysis.  \nResults: A pooled analysis of 61 trials revealed that Cr supplementation significantly increased FFM (weighted mean difference [WMD]: 1.39 kg; 95% confidence intereval (CI): 1.07,1.70; p \u003C 0.001) and body mass (WMD: 0.89 kg; 95% CI: 0.76,1.01; p \u003C 0.001) without significant effects on FM, BMI, and BFP. Trained individuals exhibited greater, though non-significant, gains in FFM (1.82 vs. 1.23 kg) compared with untrained participants, despite similar increases in total body mass. Dose–response analyses identified significant relationships between Cr dose and changes in body mass and BMI. Furthermore, supplementation duration was associated with changes in BFP and body mass.  \nConclusion: Both novice and experienced lifters gained FFM with Cr supplementation compared to placebo. The increase in FFM was approximately 0.6 kg (≈50%) greater inexperienced participants; however, this between-group difference was not statistically significant.  \nARTICLE HISTORY  \nReceived 18 April 2025 Accepted 3 November 2025  \nKEYWORDS  \nCreatine; body composition; fat-free mass; muscle hypertrophy; resistance training  \n1. Introduction  \nCreatine (Cr) is among the most extensively investigated and effective ergogenic aids [1] . In contrast to several other ergogenic aids [2–4], Cr supplementation has been demonstrated to improve body composition [5] . When combined with resistance training (RT), Cr supplementation consistently results in significantly greater increases in fat-free mass (FFM) compared to training alone [6–8] . Meta-analyses have quantified these benefits, indicating that individuals who supplement with Cr during a structured training program gain, on average, 1–2 kg more lean tissue than those receiving a placebo [5,7] .
