The Claim

In clinical trials, gastrointestinal or abdominal side effects occur in 5.51% of individuals taking creatine and 4.05% of those taking a placebo, with no statistically significant difference (p=0.820), indicating that creatine supplementation does not increase the risk of digestive discomfort.
