creatine slows bone mineral density loss in postmenopausal women
In plain terms: Can creatine protect your bones?
Part of: 🧪 creatine
Possibly, for postmenopausal women who also strength-train — a year-long trial slowed hip bone loss. But another review found no boost to bone density, and nearly all the evidence comes from one research group. A cautious maybe.
Evidence ladder
How far up the ladder this claim has climbed. A high consensus on a low rung means "consistent so far," not "proven in people."
Top evidence so far: Human trials (RCT / n-of-1)
How the studies fall
What the evidence shows
A 12-month RCT (creatine + resistance training) attenuated hip bone loss and improved bone geometry in postmenopausal women — but a systematic review found no greater *areal* BMD than training alone, and nearly all the direct evidence comes from one research group (Candow/Chilibeck). Real but modest, training-dependent, and network-concentrated — graded leans-support/contested. scope::postmenopaus

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).
