Does Creatine Sleep Meta-Analysis work?

The current Migaku evidence database contains 2 reusable source documents for Creatine Sleep Meta-Analysis. This answer focuses on strength of evidence and what the studies can or cannot prove. - This analysis investigated whether the dose or duration of CrM was associated with SEs. [Gonzalez DE (2026); evidence level 2] - Although dose and duration tertiles were statistically associated with study-level side effect reporting, the effect sizes were uniformly small, events were infrequent, and the reported symptoms were primarily mild and nonspecific. [Gonzalez DE (2026); evidence level 2] - No consistent exposure-response pattern indicative of clinically meaningful risk was observed. [Gonzalez DE (2026); evidence level 2] - There are concerns that high-dose and/or long-term creatine monohydrate supplementation (CrM) leads to greater side effects (SEs) compared to placebo. [Gonzalez DE (2026); evidence level 2] - [] identified improvements in muscular strength, repeated sprint performance, power output, and fatigue resistance due to increased PCr availability, providing strong scientific support for creatine supplementation in athletic populations. [Kerksick Chad (2026); evidence level 3] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational.
