Key Takeaway
Creatine supplementation combined with resistance training significantly improves muscle strength in healthy older adults.
A meta-analysis evaluated the efficacy of creatine supplementation in older adults aged 60 and above. The study compared the combination of creatine and resistance training against resistance training alone or a placebo plus exercise. The primary focus was on improving muscle strength, while secondary outcomes included muscle mass and physical function.
Results indicated that adding creatine to a resistance training regimen led to statistically significant improvements in muscle strength compared to training alone. The effect size was moderate, suggesting a measurable benefit for this specific metric in the studied population. However, the evidence for these improvements was categorized as moderate certainty.
In contrast, the findings for muscle mass and physical function did not reach statistical significance. While the effect sizes for these secondary outcomes were notable, the confidence intervals were wide, leading to low and very low certainty of evidence, respectively. These results suggest that while strength improves, other physiological markers may not change significantly.
Clinicians should note that these findings are specifically applicable to generally healthy older adults. The results may not be extrapolated to individuals who are frail, sarcopenic, or have significant functional limitations. Creatine may serve as a useful adjunct to traditional exercise programs for strength gains.
How this fits prior evidence
This meta-analysis extends prior evidence regarding creatine's role in muscle health. It builds upon findings that creatine may modestly increase lean mass and strength in postmenopausal women and that creatine with resistance training can support lean mass gains. It also aligns with evidence that creatine increases anaerobic power in healthy men. This study specifically addresses the impact on muscle strength in older adults, providing a more targeted look at the population compared to the broader adult and postmenopausal cohorts previously covered.
A review of several studies looked at how creatine works for older adults aged 60 and over. Researchers compared people who took creatine while doing resistance training against those who only did resistance training or took a placebo with their workouts.
The analysis found that adding creatine to a workout routine led to significant improvements in muscle strength. However, the study did not find a statistically significant increase in muscle mass or overall physical function. These results suggest that while creatine helps with strength, its impact on size and movement is less clear.
It is important to note that these findings are based on a meta-analysis and may not apply to everyone. The results are specifically for generally healthy older adults. The study notes that these findings should not be assumed to apply to those who are frail or have significant physical limitations. Talk to your doctor to see if this approach is right for your specific health needs.
What this means for you:
Creatine may help healthy older adults gain muscle strength when combined with resistance training.
Common questions
Does creatine help with muscle strength in older adults?
Yes, the study found that creatine supplementation combined with resistance training significantly improved muscle strength in adults aged 60 and older compared to those who only performed resistance training. The evidence for this specific improvement in strength is considered to be of moderate certainty.
Will taking creatine increase muscle mass for seniors?
The study did not find a statistically significant increase in muscle mass for older adults who took creatine and performed resistance training. Because the evidence for muscle mass is considered low, it is not a certain outcome for everyone.
Is this treatment safe for all older adults?
The study focused on generally healthy older adults. The researchers noted that these findings should not be directly applied to individuals who are frail, sarcopenic, or have limited physical function. You should consult a healthcare provider to determine the best plan for your specific health status.
ObjectiveTo systematically evaluate the additional effects of creatine supplementation combined with resistance training, compared with resistance training alone, on muscle strength, muscle mass and physical function in older adults.MethodsPubMed, Embase, the Cochrane Library and Web of Science were searched from inception to 20 May 2026. Randomized controlled trials enrolling older adults aged 60 years and older and comparing creatine supplementation plus resistance training with resistance training alone or placebo plus resistance training were included. Three-level random-effects meta-analyses were conducted using the metafor package in R, allowing multiple correlated effect sizes from the same study to be retained while accounting for their statistical dependence. Risk of bias was assessed using the ROBUST-RCT tool, and the certainty of evidence was evaluated using the GRADE approach.ResultsEleven randomized controlled trials were included. Three-level meta-analysis showed that creatine supplementation combined with resistance training significantly improved muscle strength compared with resistance training alone, although the effect size was small (g = 0.31, 95% CI 0.18 to 0.45); the certainty of evidence for this outcome was moderate. The pooled effects on muscle mass (g = 0.35, 95% CI −0.09 to 0.78) and physical function (g = 0.47, 95% CI −0.08 to 1.03; p = 0.086) were not statistically significant, with low and very low certainty of evidence, respectively. Moderator analyses did not identify creatine dose, loading phase, intervention duration, training frequency, training intensity, sex or testing site as stable sources of effect variation. Sensitivity analyses indicated that the main findings were not materially influenced by any single effect size or study.ConclusionIn generally healthy older adults, creatine supplementation may serve as an adjunct to resistance training for modest improvements in muscle strength. Its additional effects on muscle mass and physical function remain uncertain. These findings should not be directly extrapolated to frail, sarcopenic or functionally limited older adults. Larger, well-reported randomized controlled trials are needed in these higher-risk older adult populations.Systematic review registrationhttps://www.crd.york.ac.uk/PROSPERO/view/, identifier CRD420261417231.
