The Claim

Six weeks of supplementation with 10 grams of creatine monohydrate and 2 grams of guanidinoacetic acid has no effect on overall memory recall or recognition accuracy in the Word Recognition or Picture Recognition tests, although it is associated with modest improvements in reaction time.

Description
1 study reviewed
In plain English

Taking 10 grams of creatine monohydrate and 2 grams of guanidinoacetic acid daily for six weeks does not improve memory recall or accuracy on word and picture recognition tests, but it is linked to slightly faster reaction times.

See the scientific wording

Six weeks of supplementation with 10 grams of creatine monohydrate and 2 grams of guanidinoacetic acid does not improve overall memory recall or recognition accuracy in the Word Recognition or Picture Recognition tests, despite modest improvements in reaction time.

Why this might work

Taking creatine and guanidinoacetic acid increases the brain's stored energy, which lets nerve cells fire faster and respond more quickly to tasks, but it does not help the brain store or recall more information.

  1. Study: Effects of 6 weeks of high-dose creatine monohydrate supplementation with or without guanidinoacetic acid on cognitive function

    Taking these two supplements for six weeks didn't help people remember more words or pictures, even though they got faster at answering questions. So the claim is right: memory didn't improve.
