The Claim

Creatine supplementation improves brain health.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

Taking creatine supplements is associated with improved brain health.

See the scientific wording

Creatine supplementation improves brain health based on current peer-reviewed scientific research.

Why this might work

Creatine enters the brain and gets converted into a high-energy molecule that quickly replenishes the brain's main fuel source. This extra fuel helps brain cells work harder during demanding tasks like remembering things or solving problems, especially when energy needs are high.

What the research says

3 studies

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

    Taking creatine supplements might help your brain a tiny bit with memory, but it’s not a big change—like remembering one extra number in a game. It’s not proven for sure, but it doesn’t hurt either.

  2. Study: Effects of six weeks of high-dose creatine monohydrate supplementation with or without guanidinoacetic acid on homocysteine and markers of health

    Taking creatine lowered two blood markers linked to brain health—homocysteine and blood sugar—without causing harm, which suggests it might help the brain work better, even though they didn’t test memory or thinking directly.

  3. Study: Effects of creatine supplementation on memory in healthy individuals: a systematic review and meta-analysis of randomized controlled trials

    Taking creatine supplements helped older people remember things better, but didn't help young people much. Overall, it slightly improved memory, which is part of brain health, so yes, it seems to help.
