Why the rating is limited: evidence does not test this exact claim.

Most of the evidence behind this score addresses a related question rather than this exact claim. It can inform the answer, but cannot justify a strong conclusion on its own.

Before this limit: strong support. Final rating: leans support.

Yes for strength and muscle when combined with resistance training, which everyday tasks rely on. Trials measuring everyday function directly are fewer and less consistent, so the benefit to function itself is less certain.

🧭 Read this score with how it was built in mindWe re-read the papers behind these claims and corrected how each one is counted

Up to strong support on the score, and the summary tells you what carries it: meta-analyses of creatine plus resistance training show more lean mass and more strength than training alone. The trials that measured everyday function directly (chair rises, walking, stair climbing) are mixed. Two supporting analyses come from one research network and are counted once. Until indirect evidence has its own rule, read this as 'strong for strength and muscle, unsettled for function'.

🧭 Read this score with how it was built in mindWe re-read the papers behind these claims and corrected which ones are entitled to count

In August the two supporting analyses from one commercially-linked research network were merged so they vote once. The verdict did not move then; it moved in September for a different reason, described in the note for that wave.

🧭 Read this score with how it was built in mindStudies that measured a neighbour of the claim can no longer carry a strong verdict

Seven of the ten counting studies pooled strength or lean mass rather than a test of everyday function, or tested creatine combined with HMB. The two that measured function directly disagree: one small pooled analysis found a better chair-stand result, a larger one found no added benefit.

What the evidence shows

Creatine with resistance/weight-bearing training improves physical function in older adults. The raw score reads strong, but the headline is capped to leans-support because more than half of the weight is carried by strength and lean-mass surrogates, now marked indirect: meta-analyses of creatine plus training versus training alone find roughly 1.3-2.

meta-analysis contradicts low [Clean null on a directional 'improves function' claim = contradicts] Function narrated, NOT pooled (secondary outcome in 2-4 of 7 RCTs, postmenopausal women ~62 y): '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' - in Lobo's trial 'both groups improved TUG by ~0.5 s, with no between-group difference'; chair-rise 'creatine did not augment training-related gains'; 12-min walk 'increased similarly in both groups'; falls ~25% in each arm (p=0.8). Single exception: Chilibeck 2023 'reported a significantly greater increase in walking speed for the creatine group'. Authors' GRADE: 'Physical function-low certainty ... an effect cannot be distinguished from the absence of evidence.' Lean-mass (+0.37 kg) and leg-press (+7.5 kg) results belong to other endpoints.

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.'

meta-analysis supports moderate INDIRECT (strength surrogate; no functional test was pooled). MA of creatine + exercise vs placebo + exercise in older adults (20 articles / 1093 participants; discussion says 18 RCTs). Outcomes 'selected for meta-analysis were one-repetition maximum (1RM), fat percentage, and bone mineral density (BMD)': 1RM 'mean difference = 2.122, Z = 3.255, P = 0.001' (I2 0%; significant for leg press and lat pull-down, not arm curl, bench or chest press). The authors' 'functional performance' conclusion rests on 1RM. Authors: 'the included studies were of moderate quality according to the Cochrane RoB 2 tool, the results of the present study should be interpreted with caution.'

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 the paper does not say from the abstract.

RCT tested-null low Secondary analysis of a 30-person (62.7 y) randomized crossover trial of 3 g/day creatine + 3 g/day HMB vs placebo during training. 'Primary endpoints were oxidized glutathione and the Glutathione Redox Index'; functional tests 'were not analyzed as efficacy outcomes. Instead, they were used exclusively to derive percent changes (Δ%) for exploratory associations with redox biomarkers', and 'no absolute values or efficacy interpretations are reported, as these have been previously published for this cohort'. Redox effects did not survive FDR adjustment. Off-scope for function; the cohort's function efficacy votes via s41511610. Combination product (creatine + HMB).

meta-analysis supports moderate INDIRECT (surrogates only - no physical-function outcome pooled). Candow-network MA updating the group's 2017 MA: creatine + RT vs placebo + RT in adults >50; lean tissue mass '16 RCTs with 18 treatment arms ( n = 509) ... mean difference = 1.32 kg [95% CI: 0.93, 1.72]'; chest press SMD 0.28 [0.09, 0.47] (17 RCTs, n=456); leg press 'standard mean difference = 0.20 [95% CI: 0.00, 0.39] p = 0.05'. Leg/chest press gains lost significance when loading-phase trials were excluded. Fixed-effects model; funnel plots inspected visually only; authors report creatine-industry ties.

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.

meta-analysis supports low SR/MA of 33 RCTs (1076 participants; older adults AND adults with chronic disease - partly a proxy population; training not required). Primary outcome sit-to-stand: 'From six trials reporting the primary outcome, the pooled standardized mean difference (SMD) was 0.51 (95% confidence interval [CI]: 0.01-1.00; I 2 = 62%; P = 0.04); using weakly informative priors, the posterior probability that creatine supplementation improves physical function was 66.7%.' Small, imprecise, but the interval excludes zero - supports. Authors: 'The quality of evidence for all outcomes was low or very low because of a high risk of bias.' (Abstract-grade record.)

meta-analysis supports moderate SR/MA of 22 RCTs in older adults: resistance training + a nutritional intervention vs training alone. Creatine subgroup: lean body mass MD +2.61 kg (95% CI 0.51 to 4.72; 4 trials, I2 9%) and knee-extension strength SMD 0.74 (0.09 to 1.38; 2 trials); no creatine-specific chair-stand or timed-up-and-go estimate reported. The overall null (e.g. chair stand MD -0.13, -0.43 to 0.17; 7 trials) pools protein, multi-nutrient, omega-3, vitamin and other supplements - off-object for creatine. Authors: 'Only creatine showed synergistic effects with resistance training on muscle mass.' Creatine-specific findings all favour the claim, but on surrogates (lean mass, strength) rather than physical function itself: supports, indirect.
