Peter Attia
Physician focused on longevity and healthspan.
Should I take creatine?
Yes, for almost everyone. 5g monohydrate daily, no loading phase needed.
Should I take rapamycin?
For healthy adults at standard weekly doses: Partially Supported. For those with kidney issues or active infection: not without a physician.
Should I do Zone 2 cardio?
Yes. 3 sessions/week × 45 minutes at 60–70% max HR.
Should I wear a continuous glucose monitor (CGM)?
Watch — for healthy adults without diabetes, the n=1 data is interesting but not yet linked to better outcomes.
Should I take NAD+ supplements or IV NAD+?
Ignore IV NAD+. NMN/NR oral supplements: Watch.
Should I lift 3× per week?
Yes. Compound lifts, progressive overload. The single highest-evidence longevity intervention.
5 g of creatine monohydrate daily improves muscle strength and lean mass in healthy adults at standard training loads.
Creatine improves cognitive performance, especially under sleep deprivation and high cognitive load.
Creatine supports bone-mineral density in post-menopausal women when paired with resistance training.
Rapamycin extends median and maximum lifespan in mice across multiple lab strains and dosing protocols.
Weekly rapamycin dosing in healthy adults shows favorable safety and immune markers in early observational data.
mTORC1 inhibition is the mechanistic backbone for rapamycin's healthspan effects in mammals.

Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
