Why Creatine After 40
The Most Studied Supplement for Healthy Aging
Keep the Strength You Built
After 40, you lose 3–8% of muscle mass per decade. Meta-analyses across thousands of older adults confirm significant gains in strength and lean mass when creatine is combined with resistance training. This is not about getting huge — it's about not getting weak.
A Sharper Mind, Every Day
Your brain burns 20% of your daily energy. 2025 systematic reviews show measurable improvements in memory and attention in adults over 40 supplementing with creatine. The same molecule powering your muscles is fueling your focus and clarity.
Energy That Lasts Past 2 PM
Creatine replenishes ATP — every cell's energy currency. Users consistently report less afternoon fatigue, faster recovery, and steadier daily energy. Not a caffeine spike. Not a crash. Just more capacity to do what you want.
Protect Your Frame From Within
Emerging research on osteosarcopenia shows creatine combined with resistance training produces synergistic effects on bone mineral density. You're not just maintaining muscle — you're reinforcing the entire structure that keeps you active for decades.

Straight Answers to Common Questions
Isn't creatine just for bodybuilders?
That's the outdated reputation, not the science. Research actually shows the broadest and most meaningful benefits in adults over 40 — particularly for muscle preservation, cognitive function, and energy. Younger athletes get marginal gains. Older adults get transformational ones.
Is creatine safe for my kidneys?
This concern has been studied exhaustively for over three decades — across thousands of participants — and no adverse kidney effects have been found in healthy adults. The myth originated from a single misinterpreted case study in the 1990s. Every major sports nutrition body has since confirmed creatine's safety at recommended doses.
Will I get bloated?
At the standard 5g daily maintenance dose, water retention is minimal and typically unnoticeable. The bloating stories come from outdated "loading phase" protocols using 20g+ per day. No loading phase is needed with Thorne. One scoop, every day — that's it.
Why Thorne instead of a cheaper brand?
Because you don't know what's in a cheaper brand. Thorne is NSF Certified for Sport, meaning every batch is independently tested for purity. They use Creapure® creatine from Germany — the same source researchers use in clinical trials. At $0.46 per day for a 3-month supply, the premium for certainty is negligible.
