The Claim
Creatine supplementation at 5 g/day for 24 weeks has no significant effect on cognitive function in healthy older adults.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking 5 grams of creatine daily for 24 weeks does not change cognitive function in healthy older adults.
See the scientific wording
Creatine supplementation for 24 weeks at 5 g/day showed no significant effect on cognitive function in healthy older adults, based on a randomized controlled trial with 134 participants comparing creatine, placebo, and creatine combined with resistance training.
Creatine enters the brain and gets converted into a high-energy molecule that quickly replenishes the brain's main energy source when neurons are active. This keeps brain cells powered during thinking tasks, but in healthy older adults, their brains already have enough energy to meet these demands, so extra creatine does not improve thinking.
What the research says
1 studyStudy: Creatine and Cognition in Aging: A Systematic Review of Evidence in Older Adults
The Alves et al. RCT was the only high-quality intervention study in the review, using a 24-week, double-blind, placebo-controlled design with 134 participants. It found no significant cognitive improvements from creatine supplementation alone or combined with resistance training, directly contradicting the positive associations seen in observational studies.
