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.

meta-analysis tested-null low Physical function was measured but NOT pooled, and this row's own endpoints were null: 'For the timed up-and-go (TUG) test, two studies reported small improvements over time with resistance training, with no additional benefit of creatine versus placebo'; chair-rise/timed-stand 'creatine did not augment training-related gains'; 12-min walk no intergroup difference; falls ~25% in each arm (p=0.8). One exception: Chilibeck 2023 found a significantly greater increase in walking speed. Authors' own GRADE: 'Physical function-low certainty ... an effect cannot be distinguished from the absence of evidence.' The lean-mass (+0.37 kg) and leg-press (+7.5 kg) results previously stored here belong to other endpoints and do not bear on function.

meta-analysis supports low Meta-analysis of randomized placebo-controlled trials, 357 older adults (~64 yr), 12.6 ± 4.9 wk of resistance training. The functional endpoint was pooled directly: 'Cr + RT had a greater effect than RT alone on the 30-s chair stand test (P = 0.03).' Body composition and compound-lift strength also favoured creatine, but four strength endpoints (knee extension and biceps curl 1RM, isokinetic and isometric knee extension peak torque) were null. Authors caveat: 'the limited number of studies indicates further work is needed.'

RCT supports low 16-wk randomized, double-blind, placebo-controlled trial (NCT06620666), 103 older adults (68.2 +/- 4.6 y) in six arms crossing elastic-band / aquatic / no-training with creatine 3 g/d or placebo (~17 per cell). Physical function was measured by timed up-and-go, 30-s chair-stand and 6-min walk. 'Creatine provided additional benefits, increasing GPx, reducing IL-6/TNF-alpha and improving strength and function when combined with exercise modalities.' Two cautions on the prior wording: the p<0.05 in the abstract attaches to the TRAINING effect ('Both training modalities produced significant improvements ...'), not to the creatine contrast, which is reported narratively without statistics; and the creatine function benefit is stated only in combination with exercise - the creatine-alone arm's reported gains were F2-isoprostanes, TNF-alpha and perceived health, so creatine monotherapy on physical function is cannot-tell from the abstract.

meta-analysis mixed low Meta-analysis of 8 RCTs, n = 176 older females, creatine + RT vs placebo + RT, 12-52 weeks. NO functional endpoint was pooled - the outcomes were 1RM chest/leg press strength and muscle mass; the link to daily function is the authors' discussion-level inference from an external citation, not a measured result. Mixed on what it did measure: 'Overall, Cr significantly increased measures of upper-body strength (7 studies, n = 142, p = 0.04), with no effect on lower-body strength or measures of muscle mass.' The muscle-mass result is explicitly null - 'Cr, independent of study duration, had no effect on measures of muscle mass ( Figure 4 )' - correcting the previous extract, which claimed creatine improved muscle mass. Authors' conclusion: 'Cr + RT in a small cohort of older females enhanced muscle strength when the duration was at least 24 weeks; however, there was no effect on muscle mass. Overall, the certainty of the evidence is low.' Quality set to low to match that GRADE rating.
