Creatine supplements have limited effects on brain function

What the research says

3 studies

  1. Study: The Effect of Creatine Monohydrate on Mental Disorders: A Systematic Review of Randomized Controlled Trials: Effet du monohydrate de créatine sur les troubles mentaux : examen systématique des essais contrôlés à répartition aléatoire

    Taking creatine helped some adults with depression feel better when combined with their medication or therapy, and it changed brain chemicals linked to that improvement — so it does affect the brain in some cases, contrary to the claim.

  2. Study: Single-Dose Creatine Reduces Sleep Deprivation-Induced Deterioration in Cognitive Performance

    Taking creatine helped people think better when they were sleep-deprived, improving their logic and reaction speed by up to 12%. This means creatine does affect brain function — it’s not just a muscle supplement.
