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.
