Published in BMC Medicine
Methodology
Randomized, double-blind, placebo-controlled crossover trial of creatine 5 g/day for 6 weeks in healthy adults, assessing Raven's Advanced Progressive Matrices and backward digit span.
Key Findings
Creatine produced no statistically significant improvement in the primary cognitive outcomes compared with placebo in healthy, mostly omnivorous adults.
Conclusions
Six weeks of creatine supplementation did not improve cognitive performance in healthy adults.
Limitations
Predominantly omnivorous, well-rested participants may have had little headroom for benefit; standard rather than high-dose protocol.
Supplements Studied
Creatine produced no statistically significant improvement in the primary cognitive outcomes compared with placebo.
Outcomes Measured
Creatine produced no statistically significant improvement in the primary cognitive outcomes compared with placebo.
