Creatine and aging answer
A peer-reviewed Geebs Science answer on creatine, resistance training, lean mass, strength, aging, and supplement honest study limits.
Kris Oddo, NASM-certified personal trainer, is the founder and head coach of Gains From Geebs (Geebs Coaching), a 1:1 online fitness coaching practice.
Short answer
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.
How strong is this kind of study?
Meta-analysis. Heavier plates are built from more studies, so they move less when the next one lands.
Try this
If you are healthy and cleared to use it, keep it boring: creatine monohydrate, consistent daily use, and no expectation that it replaces hard progressive training.
Honest limits
Creatine research in healthy adults does not establish safety for every person. People with kidney disease, medication concerns, or other medical conditions should talk to a clinician before using it.

Studies behind this answer
Creatine belongs behind the boring hierarchy: train hard, progress the lifts, then use creatine as support.
Creatine is worth discussing for adults who lift, but the supplement sits behind the actual training, protein, and recovery stack.
Anti-aging is the reason to lift that feels responsible, not vain.
Adequate protein can support lean mass and strength when it is paired with training.
Resistance training supports staying strong and capable as you age; it is not only about appearance.

FAQ
For physique goals, creatine is most useful when it supports a real resistance-training program. It is not a shortcut around training.
Plain creatine monohydrate is inexpensive and the best-studied form. Product choice should still account for quality, tolerance, health history, and medications.
No supplement is for everyone. Healthy adults usually tolerate creatine well, but kidney disease, medication concerns, or clinical context should be cleared with a clinician.
More Anti-aging questions
Strength and aging answer
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
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
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 training answer
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.
Brain-aging exercise answer
Exercise is not just for body composition. Reviews of exercise and cognition support movement as part of a healthy-aging routine, but exercise is not a treatment for cognitive disease.
Biological aging answer
Exercise is one of the strongest practical healthy-aging levers, but workouts do not reverse time. Physical activity, strength, and cardio are still among the most actionable ways to support health and function as you age.
