The Claim
No study in this review objectively measured brain or blood creatine levels, so it is unknown whether dietary intake or supplementation increased creatine concentrations in the brain.
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.
No study in this review measured creatine levels in the brain or blood, so it cannot be determined whether eating or supplementing with creatine raises creatine concentrations in the brain.
See the scientific wording
No study in this review objectively measured brain or blood creatine levels, so it is unknown whether dietary intake or supplementation actually increased creatine concentrations in the brain, limiting interpretation of cognitive associations.
Creatine moves from the blood into the brain, where it is converted into a high-energy molecule that constantly recharges the brain's energy supply. This keeps brain cells running during demanding mental tasks.
What the research says
1 studyStudy: Creatine and Cognition in Aging: A Systematic Review of Evidence in Older Adults
The study didn’t measure how much creatine was in people’s brains or blood, so we can’t be sure if eating or taking creatine actually raised those levels. This matches the claim exactly.
