creatine slows bone mineral density loss in postmenopausal women

In plain terms: Can creatine protect your bones?

consensus score -0.57

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.

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.

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.
