Creatine helps older lifters — but only alongside the training

Creatine's credentials in young athletes and bodybuilders are well established — hypertrophy, strength, power and endurance are all documented. What has been far less clear is whether those benefits carry over to an ageing population training at a moderate level, and how gender, dose and duration shape the answer. Since muscle, bone and cognitive health all decline with age, knowing whether a cheap, widely available supplement genuinely adds anything on top of exercise in older adults is a question with real practical stakes.

The reviewers searched PubMed, CINAHL and Web of Science for randomised controlled trials combining creatine supplementation with exercise in an ageing population, applying predetermined inclusion and exclusion criteria. Two reviewers independently screened titles and abstracts, assessed full texts, and rated study quality using the Physiotherapy Evidence Database (PEDro) scale. Seventeen studies were comprehensively reviewed, organised into categories covering strength, endurance, functional capacity, body composition, cognition and safety.

The reviewed trials suggest that any additive creatine effect on upper- and lower-body strength, functional capacity and lean mass in older adults requires continuous, daily low-dose supplementation combined with at least 12 weeks of resistance training. Potential creatine-specific increases in regional bone mineral density of the femur are possible but may require at least a year of supplementation alongside moderate resistance training, with further long-term trials needed. The limited data showed no additive effect of creatine over exercise alone on mental health indices. Benefits were more consistent in older women than men, and creatine monohydrate was judged safe for older adults.

This review extends creatine's well-documented ergogenic profile from young athletes towards older exercisers, but with important conditions attached: the training stimulus appears essential, and the timeframes are longer than the acute effects seen in younger populations. The apparent gender difference — more consistent benefits in older women — is an intriguing thread the authors flag rather than resolve. The absence of pooled effect sizes, the heterogeneity of trial protocols, and the unresolved questions of optimal dose and duration for bone and cognition all mean firmer answers await further long-term trials.

If you are an older adult already doing resistance training — or thinking about it — this review is a reason to see creatine as a potential supporting act rather than a shortcut: the trials suggest any added benefit shows up only alongside a sustained programme of at least 12 weeks of resistance work. The safety record in this age group was reassuring, and the signal was notably more consistent in women. It is not a substitute for training, and questions about the ideal dose and duration remain open.
