Peer-reviewed study
Creatine worked best behind hard resistance training
Effects of high-load, velocity-intentional variable resistance training combined with creatine supplementation on neuroplasticity, oxidative stress, inflammation, physical function, cognitive performance and quality of life in older adults: A randomized, double-blind, placebo-controlled trial

Honest limits
What this study does not prove.
This study combined creatine with training in older adults, so it does not establish creatine as a stand-alone anti-aging treatment.
Kris's practical takeaway
Here's what to do with it.
Creatine belongs behind the boring hierarchy: train hard, progress the lifts, then use creatine as support.
Ways to use it
Safe ways to apply it.
Creatine is support, not the plan
Power training matters as you age
Supplements make more sense behind training
Related questions
Questions this research helps answer.
Strength and aging answer
Does strength training help you age better?
Strength training is one of the most practical healthy-aging levers because it supports muscle, function, and physical capacity. Lifting does not reverse aging, but keeping strength and muscle can make aging more resilient.
Brain health and aging answer
Does resistance training help brain health as you age?
Resistance training can support strength, function, inflammatory markers, and some brain-health signals in older adults. It is not an age-reversal treatment and does not guarantee protection from cognitive decline.
Creatine and brain health answer
Does creatine help brain health as you age?
Creatine is interesting for healthy-aging research, but it is not a brain-health shortcut. It makes the most sense behind consistent resistance training, sleep, nutrition, and recovery.
Creatine and aging answer
Should men over 30 take creatine?
Creatine is one of the more defensible supplements for trained adults, but it is still support, not the plan. The useful hierarchy is resistance training, protein, sleep, then creatine if it fits health context and consistency.
Creatine and training answer
Does creatine work without lifting?
For muscle and physique goals, creatine works best as support for resistance training. It may change water storage and help performance, but it is not a stand-alone muscle-building plan if you are not lifting.
Creatine and lifting answer
Do creatine and lifting change body composition?
Creatine can support resistance-training outcomes for strength and lean mass, but it works as support for training, not as a replacement for training. The boring interpretation is the useful one.
Creatine aging answer
Does creatine help aging adults?
Creatine may help support training-related outcomes in older adults, but it works best as support for a strength plan, not as a replacement for one. The boring stack still wins: lift, eat enough protein, sleep, and stay consistent.
Creatine cognition answer
Does creatine help brain aging?
Creatine has aging and cognition research worth following, but it is not a brain-aging cure. It is a possible support for training, sleep, and nutrition — not a replacement for those basics or for medical care.
