Systematic Review With Meta-AnalysisMeta-analysis2025
When older adults take creatine and do strength training, they get noticeably stronger—like being able to lift heavier weights. This means their muscles are working better, which helps them stay active and independent as they age.
Randomized Controlled TrialHuman2016
Taking creatine along with strength training helped older adults gain more muscle than those who only did strength training. So yes, creatine helps keep muscle mass as people age.
Cross-Sectional StudyHuman
This study found that older adults with Alzheimer’s who took creatine for eight weeks gained a tiny bit of muscle in their legs, even though they weren’t exercising. This suggests creatine might help older people keep their muscles from getting weaker.

That doesn't mean it's settled — it just means no study has tested the opposite.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.
Creatine builds up in muscle cells and helps make more energy quickly during exercise, allowing for harder and longer workouts. This increased effort triggers muscle cells to build more protein and grow larger. At the same time, creatine helps muscle cells take in more sugar from the blood and store it as fuel, which keeps the muscles healthy and working well. Larger, healthier muscles produce more strength and keep older people moving independently.
