Evidence review: Creatine improves cognition, especially memory
Meta-analyses find small but consistent improvements in memory and reasoning, with the largest effects in older adults and in sleep-deprived states.

Creatine improved memory (SMD = 0.29) with significant effects in older adults (66-76 years) versus younger individuals.
What pushes back.
Caveats, null findings, and methodological limits that hold the tier where it is.
What the evidence supports.
What we recommend
5 g/day, same as the strength dose. Effects on cognition take 4 weeks or more to appear as brain creatine pools fill. 2,3

Common questions.
Quick answers drawn from the verdict, evidence, and recommendation above.
Does the evidence support the claim that creatine improves cognition, especially memory?
Meta-analyses find small but consistent improvements in memory and reasoning, with the largest effects in older adults and in sleep-deprived states.
How strong is the evidence behind Creatine and Creatine Monohydrate for this claim?
NutriStack rates this as Moderate evidence, meaning several aligned RCTs or one large RCT plus supporting reviews. Full tier criteria are at https://nutristackapp.com/methodology/evidence-tiers.
What contrary evidence or caveats apply?
Effect on healthy young adults is small. Most trials are short (4 to 8 weeks).
What does NutriStack recommend?
5 g/day, same as the strength dose. Effects on cognition take 4 weeks or more to appear as brain creatine pools fill.

This is how NutriStack presents an evidence review.
Each published claim review shows its verdict, attached studies, contrary evidence, dose context, and limits. Coverage is selective rather than a claim that every database assertion has received the same review.
