The Claim
Six weeks of daily supplementation with 10 grams of creatine monohydrate and 2 grams of guanidinoacetic acid significantly improves YES reaction time by 28.7% and overall reaction time by 18.1% in healthy, recreationally active adults aged 26–55.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In healthy adults aged 26–55 who are recreationally active, daily intake of 10 grams of creatine monohydrate and 2 grams of guanidinoacetic acid for six weeks reduces reaction time in cognitive tasks by 28.7% for YES responses and by 18.1% for overall responses.
See the scientific wording
Six weeks of daily supplementation with 10 grams of creatine monohydrate and 2 grams of guanidinoacetic acid significantly improves YES reaction time by 28.7% and overall reaction time by 18.1% in healthy, recreationally active adults aged 26–55, suggesting that combined supplementation enhances speed of response in cognitive tasks requiring rapid decision-making.
Taking creatine and guanidinoacetic acid every day for six weeks increases the amount of high-energy fuel in brain cells. When the brain needs to make quick decisions, this extra fuel lets it recharge its energy supply faster, so neurons can fire and communicate more rapidly, leading to quicker reaction times.
What the research says
1 studyThis study found that adults who took 10 grams of creatine and 2 grams of another chemical every day for six weeks got faster at answering simple yes-or-no questions on a computer test. Their reaction times improved significantly, just like the claim says.
