A 12-week study reported by ScienceDaily found that middle-aged adults who took creatine gained muscle and strength even without following a structured workout program. The finding points to creatine as a potential standalone intervention for preserving or building muscle in this age group.
The same study showed that combining creatine with exercise and a calorie-reduced diet led to even greater strength gains. Participants in that combined group also added lean tissue and lost fat, suggesting the supplement may enhance body-composition changes when paired with lifestyle modifications.
These results come from a single trial summary, and the available report does not include details such as dosage, participant health status, or the exact exercise protocol. Still, the findings add to evidence that creatine's benefits may extend beyond its common use as a workout supplement.
