Creatine spent 30 years as a bodybuilder’s powder. In 2026 it’s having a second act as a longevity tool. A new study found a single large dose kept sleep-deprived adults sharper on focus and reaction time; reviews point to memory and processing benefits in older adults; and a meta-analysis found adults over 50 gained ~3 lbs more lean mass with creatine plus training.
Why it matters
It’s the rare supplement that’s both cheap and evidence-backed. Most “longevity” pills are hope in a bottle. Creatine monohydrate has decades of safety data and a growing pile of trials for muscle, bone and brain — especially relevant as GLP-1 users fight to keep muscle.
The evidence-backed stack
Creatine monohydrate
Plain monohydrate, 3–5 g daily. Skip the expensive “advanced” forms — monohydrate is what the studies use.
