The Claim

Creatine supplementation at 5g/day for six weeks has no statistically significant effect on abstract reasoning performance as measured by the Raven’s Advanced Progressive Matrices in healthy young adults, with a mean effect size of d = 0.09 and p = 0.327.

In plain English

Taking 5 grams of creatine daily for six weeks does not change performance on tests of abstract reasoning in healthy young adults.

See the scientific wording

Creatine supplementation at 5g/day for six weeks does not significantly improve abstract reasoning performance on the Raven’s Advanced Progressive Matrices (RAPM) in healthy young adults, with a mean effect size of d = 0.09 and p = 0.327, indicating no meaningful cognitive benefit in this domain.

Why this might work

Creatine enters the brain and is converted into a storage form that quickly replenishes energy when brain cells need it most. Even though this energy boost happens, it does not improve the ability to solve complex logic puzzles because the brain already has enough energy for these tasks in healthy young adults.

  1. Study: The effects of creatine supplementation on cognitive performance—a randomised controlled study

    This study gave people 5 grams of creatine every day for six weeks and tested their ability to solve logic puzzles. They didn’t get any better at it than people who took a fake pill, so creatine doesn’t seem to help with these kinds of puzzles.
