Does creatine help older adults?

What the evidence shows

The evidence concerns generally healthy older adults participating in structured resistance programs. It does not show that creatine alone prevents age-related muscle loss or that every strength measure improves.^{[1], [2]}

Lean tissue gains were larger with training plus creatine

Meta-analyses of randomized placebo-controlled trials found that older adults taking creatine during resistance training gained more lean tissue or fat-free mass than those training with placebo.^[1]

One analysis included 357 adults averaging about 64 years and roughly 12.6 weeks of training. Total body mass and fat-free mass increased without a corresponding increase in fat mass.^[1]

The additional lean-mass effect was modest

The direction of the pooled results supports creatine as an adjunct, but the added lean-tissue benefit over training alone was modest.^{[1], [2]}

Lean tissue is a body-composition outcome and should not be treated as a promise of visible muscle gain, functional independence, or prevention of frailty.^{[1], [2]}

Some strength and function measures improved

Pooled results reported larger gains in chest-press and leg-press one-repetition maximum with creatine plus resistance training than with training alone.^{[1], [2]}

One analysis also found greater improvement on the 30-second chair-stand test, but knee-extension and biceps-curl outcomes did not consistently differ.^{[1], [2]}

Dosing strategy influenced some findings

Studies generally used around 5 g per day or more, sometimes after a short loading phase. In an updated analysis, some chest- and leg-press advantages depended on the loading and maintenance strategy.^{[1], [2]}

When loading-phase studies were excluded, the pooled chest- and leg-press advantages were no longer significant. This makes protocol differences an important source of uncertainty rather than a basis for a universal regimen.^{[1], [2]}

Resistance training is not optional in this evidence

The studies evaluated creatine as an addition to resistance training. The reported lean-mass and strength gains cannot be attributed to creatine used alone.^{[1], [2]}

A supplement should therefore not be presented as a substitute for progressive, appropriately supervised exercise in older adults.^{[1], [2]}

The population was generally healthy

Participants were generally healthy older adults rather than people with a specific diagnosed neuromuscular or frailty condition.^{[1], [2]}

Age-related medical conditions, medicines, fall risk, kidney function, and exercise safety can all change an individual decision and were not resolved by the pooled average.^{[1], [2], [3], [4]}

The evidence is encouraging but not definitive

The number of randomized trials was limited, and meta-analyses reported substantial between-study heterogeneity linked partly to differences in creatine ingestion strategy.^{[1], [2]}

Further work is needed to establish the size, durability, and most generalizable protocol for older adults.^{[1], [2]}
