The effectiveness of protein supplements on athletic performance and post-exercise recovery - a Bayesian multilevel meta-analysis of randomized controlled trials.
Journal of the International Society of Sports Nutrition·December 31, 2026·PMID 41433039

This meta-analysis clarifies that observed performance and recovery benefits may be largely due to increased energy intake rather than a specific protein effect, challenging common supplementation practices.
