Nutrients (2024) · Meta analysis · n=20
In comparison with a placebo, creatine supplementation combined with resistance training significantly increased upper-body (WMD = 4.43 kg, p < 0.001) and lower-body strength (WMD = 11.35 kg, p < 0.001).
Meta-analysis showed small effect (SMD=0.196) with ~3 additional reps. Several individual studies showed mixed results including null findings. Effect appears inconsistent across different exercise modalities.
Based on meta-analyses showing 5-15% strength increases. Upper-body improvements 4.43kg, lower-body 11.35kg. Effects plateau at therapeutic doses.
