Creatine aging answer
A peer-reviewed Geebs Science answer on creatine, aging, exercise training, strength, body composition, cognition, and practical supplement guardrails.
Short answer
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.
Practical move
If creatine is appropriate for you, pair it with progressive resistance training and track strength, body weight, digestion, and consistency. Do not use it as permission to skip the workouts.
Claim guardrail
This is supplement education, not medical advice. People with kidney disease, medications, pregnancy, or clinical concerns should ask a qualified clinician.
