BMC medicine ·

Human

Full paper summarizedQuality not appraised
What was studied
This preregistered randomized crossover trial tested whether creatine improved working memory, abstract reasoning and eight exploratory cognitive outcomes.
Who / model studied
The study included 123 adults; approximately half were vegetarian and half were omnivorous.
Studied dose & schedule
Participants received creatine 5 g daily and placebo for 6 weeks each in a blinded crossover design.
What the study found
The working-memory result bordered significance, while abstract reasoning and exploratory tasks did not improve. Side effects were reported more often with creatine; vegetarians did not benefit more than omnivores.
Limitations & context
The data supported, at most, a small cognitive benefit. Larger studies are needed to confirm or rule out that effect.
