“Creatine improves memory and clears brain fog in healthy adults.”
An editorial question about whether creatine supplementation improves memory or brain fog in healthy adults.
A 2024 meta-analysis of 16 trials (492 participants, including healthy people and patients) reported a small benefit for memory, but not overall cognition or executive function. Its findings are uncertain: a 2026 commentary says correlated cognitive test results from the same participants were counted as independent, potentially overstating precision. The supplied evidence does not assess “brain fog” as an outcome, so it cannot establish that creatine clears it.
If you’re considering creatine for memory or brain fog, what changes are you hoping to notice? The research has examined test performance, but it has not established that creatine clears brain fog.

What changed
November 04, 2026 A 2024 meta-analysis of 16 trials (492 participants, including healthy people and patients) reported a small benefit for memory, but not overall cognition or executive function. Its findings are uncertain: a 2026 commentary says correlated cognitive test results from the same participants were counted as independent, potentially overstating precision. The supplied evidence does not assess “brain fog” as an outcome, so it cannot establish that creatine clears it.
November 03, 2026 An EFSA review concluded that a cause-and-effect relationship between creatine and improved cognitive function has not been established. A 2023 randomised crossover trial of 123 adults found no clear benefit on reasoning or exploratory cognitive tests; a small working-memory benefit was possible but uncertain. Neither source assessed “brain fog” as a clinical outcome. The trial reported more side effects with creatine than placebo.
GPT-6 Luna The memory signal is not enough to support the full claim: the meta-analysis included mixed populations, and the later methodological critique raises a substantial concern about its analysis. Evidence here does not confirm a benefit specifically in healthy adults, and “brain fog” was not measured.
DeepSeek V4.1 Flash The meta-analysis reports a small memory benefit (SMD 0.24) from creatine, but this is low-certainty evidence and not specific to healthy adults: it pooled healthy people with clinical populations, and effects were larger in those with disease. "Brain fog" was not measured. A commentary notes a methodological flaw (counting multiple tests from the same participants as independent), which inflates precision; a similar reanalysis removed the memory effect, and an EFSA panel judged the evidence inconclusive. Bottom line: a modest, uncertain memory signal, not a proven cognitive enhancer for healthy people.
Grok 4.7 The claim is only partly supported and overstated. A 2024 meta-analysis of 16 trials reported a small memory benefit from creatine monohydrate, with moderate-certainty evidence, plus possible effects on attention and processing speed. Benefits appeared greater in people with disease than in healthy adults. Overall cognition and executive function did not improve. A later commentary identified double-counting of related test results, which can inflate significance. EFSA concluded that no cognitive claim could be drawn from those data. Brain fog was not assessed. Evidence does not justify routine use in healthy adults.
