creatine improves physical function in older adults
In plain terms: Can creatine help older adults stay strong and mobile?
Part of: 🧪 creatine
Probably, when combined with resistance training — it builds the strength and muscle that everyday tasks depend on. But trials measuring real-world function directly are mixed, so it's a lean yes, not a sure thing.

What the evidence shows
Creatine with resistance/weight-bearing training improves strength and lean mass in older adults, which supports functional tasks (sit-to-stand, gait). Benefit is training-dependent; two well-conducted syntheses judged the direct functional-disability evidence unclear, so this is graded leans-support, not settled.

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).
