Key Takeaway
Meta-analysis showing creatine supplementation increases strength gains by 8% and weightlifting performance by 14% compared to training alone.
Summary
This meta-analysis examined 22 studies on creatine supplementation combined with resistance training. The researchers found consistent, significant improvements in strength and performance measures.
Creatine supplementation increased strength by an average of 8% more than placebo groups, with even larger effects (14%) on weightlifting performance measures like 1RM. The benefits were seen across different populations and training protocols.
This study established creatine as one of the most effective legal ergogenic aids for strength training.
