The Claim
Supplementation with 10 grams of creatine monohydrate and 2 grams of guanidinoacetic acid for six weeks significantly improves correct incongruent reaction time by 38.8% in healthy adults during the Stroop test compared to supplementation with creatine monohydrate alone.
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.
Taking 10 grams of creatine monohydrate and 2 grams of guanidinoacetic acid daily for six weeks improves reaction time accuracy by 38.8% during a cognitive test that measures executive control, compared to taking creatine monohydrate alone.
See the scientific wording
Supplementation with 10 grams of creatine monohydrate and 2 grams of guanidinoacetic acid for six weeks significantly improves correct incongruent reaction time by 38.8% in healthy adults during the Stroop test compared to creatine monohydrate alone, indicating enhanced executive control under cognitive conflict.
Taking creatine and its precursor together increases the brain's energy reserves, allowing nerve cells to recharge faster when they need to send signals quickly. This lets the brain make correct decisions faster when it's distracted by conflicting information.
What the research says
1 studyPeople who took both creatine and guanidinoacetic acid together got much faster at making correct decisions when distracted, compared to those who only took creatine. The study proved this difference was real and not due to chance.
