The Claim
Daily supplementation with 5 grams of creatine monohydrate for six weeks in healthy young adults (mean age 31) is associated with a small, non-significant improvement in backward digit span performance (Cohen’s d = 0.17), with a mean increase of 0.41 correct items, and shows no significant effect on abstract reasoning (RAPM, d = 0.09) or any of eight other exploratory cognitive tasks.
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.
In healthy young adults, taking 5 grams of creatine monohydrate daily for six weeks is associated with a very small increase in backward digit span performance but no meaningful change in abstract reasoning or other cognitive tasks.
See the scientific wording
Daily supplementation with 5 grams of creatine monohydrate for six weeks in healthy young adults (mean age 31) is associated with a small, non-significant improvement in backward digit span performance (Cohen’s d = 0.17), with a mean increase of 0.41 correct items, but shows no significant effect on abstract reasoning (RAPM, d = 0.09) or any of eight other exploratory cognitive tasks, suggesting any cognitive benefit is minimal and inconsistent across domains.
When a person takes creatine daily, it enters the brain and gets converted into a high-energy molecule that quickly replenishes the brain's energy supply during mentally demanding tasks. This extra energy helps neurons fire more consistently during short-term memory tasks, making it slightly easier to remember sequences of numbers in reverse order, but it does not improve tasks that require abstract thinking or problem-solving because those tasks do not rely on the same energy bursts.
What the research says
1 studyStudy: The effects of creatine supplementation on cognitive performance—a randomised controlled study
Taking 5 grams of creatine daily for six weeks might help people remember a tiny bit more numbers in a memory game, but it doesn’t make them smarter at solving puzzles or thinking faster — and the improvement is so small it might just be luck.
