Frequently asked

How long does Creatine take to work for bone health?

Trials of Creatine for bone health typically report effects within 2–4 weeks, though individual response varies. Studies rarely find benefit inside 1 week for chronic outcomes.

What dose was used in studies of Creatine for bone health?

Studied doses for Creatine in bone health trials cluster around a moderate daily dose. See the dose block for the specific range and how it varies by form.

Does Creatine work for bone health if I'm not deficient?

The effect concentrates in post-menopausal females. If your baseline is normal, expect a smaller effect than the trial averages.

Creatine or the next-best alternative for bone health?

See the compare block above for the head-to-head with the most-cited alternative. Grade + certainty differences matter more than any single trial.
