Two complementary taxonomies for sorting longevity interventions before evaluating their evidence:
Huberman's four categories: (1) behavioral dos-and-don'ts, (2) calories/glucose/insulin/mTOR management, (3) targeting specific cellular pathways (e.g. NAD — see NAD Precursor Supplementation (NR, NMN, IV NAD)), and (4) 'kitchen sink' stacking of many interventions at once (e.g. Brian Johnson).
Attia's three categories (mutually exclusive, collectively exhaustive):
Sort any candidate intervention into one of these buckets to judge whether it addresses baseline survival behavior, a specific disease risk, or the aging process itself — and weigh the evidence bar accordingly (see Evaluating Nutrition & Fitness Evidence for the ITP/statistical-significance standard used to judge each bucket).
The Titanic analogy: emotional/mental health is the ship's heading (the dominant directional factor); sleep, exercise, and nutrition are the other essential pillars; supplement choices (like NAD precursors) are comparatively minor deck details ('lobster vs. steak') that matter far less than the overall direction. In modern society, living longer is mathematically equivalent to delaying the onset of chronic disease (cardiovascular, cerebrovascular, cancer, neurodegenerative, metabolic), since infection and childbirth complications are no longer primary mortality drivers — reinforcing why foundational behaviors dwarf any single supplement's impact.
An extension of this page's classification schemes, framed by Peter Attia for evaluating any exogenous molecule — medication or supplement — before deciding to keep taking it:
The walkthrough is capped by a risk-reward assessment — side-effect profile, effect size, confidence in the safety data, and supplement quality/sourcing — which sorts the molecule into a bucket like "low-risk, modest reward" (the bucket creatine lands in). Apply: run any supplement or medication on your own list through these six questions in order, ending with the risk-reward check, before deciding whether to keep it.
Two supporting mental models travel with this framework:
This reuses the lifespan-vs-healthspan and disease-specific-vs-geroprotective axes already on this page, generalizing them from "longevity interventions" specifically to any exogenous molecule a person takes.
