What the research says
2 studies reviewedSupporting (2)
Randomized Controlled TrialHuman2016
Taking creatine supplements helped women’s brains work better, and one key sign of this improvement is a chemical called NAA that only goes up when there’s more creatine around to help energy production. So yes, creatine pills likely raised creatine levels in their brains.
Randomized Controlled TrialHuman
Taking creatine supplements made the brains of people with Alzheimer’s have more creatine — like adding more fuel to a battery. The study measured this directly and found a clear increase.

That doesn't mean it's settled — it just means no study has tested the opposite.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.
When someone takes creatine pills, the creatine enters the bloodstream, crosses into the brain through a specific transporter, and builds up inside brain cells where it can be used to store and supply energy.
