The Claim
Creatine supplementation at 10 or 20 g/day for 6 weeks has no significant effect on prefrontal cortex oxygenation (O2Hb) during episodic memory or executive function tasks in healthy young adults.
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 creatine supplements at 10 or 20 grams per day for six weeks does not change the level of oxygen in the prefrontal cortex of healthy young adults when they perform memory or decision-making tasks.
See the scientific wording
Creatine supplementation at 10 or 20 g/day for 6 weeks does not significantly alter prefrontal cortex oxygenation (O2Hb) during episodic memory or executive function tasks in healthy young adults, indicating that any potential neurophysiological effects are task-specific and not broadly applicable across cognitive domains.
What the research says
1 studyStudy: Dose–Response of Creatine Supplementation on Cognitive Function in Healthy Young Adults
This study gave young adults either 10 or 20 grams of creatine daily for six weeks and checked if their brain’s oxygen levels changed while doing memory and thinking tasks. It found no meaningful change, meaning creatine doesn’t seem to boost brain oxygen use during these tasks.
