Questions this research helps answer.
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.
