creatine improves cognition in Alzheimer's disease
In plain terms: Does creatine help people with Alzheimer's?
Part of: 🧪 creatine
Too early to say. Just one small pilot — with no placebo group — has tested it in Alzheimer's patients. It raised brain creatine and hinted at benefit, but you can't draw conclusions from an uncontrolled study. Worth a real trial, not a recommendation.

What the evidence shows
Only one small, single-arm, placebo-free pilot (2025) has tested creatine in Alzheimer's patients — it raised brain creatine and hinted at cognitive gains, but with no control group and preclinical rationale behind it, this is early-stage. Graded insufficient until a controlled trial exists.

Disagree, or know a study we missed?
We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
Opens a short form. You'll sign in with Google so submissions are tied to a real account — we don't display your identity, and we only accept a link we can verify (PubMed, DOI, ClinicalTrials.gov).
