Longevity supplements and pathway hype
Last reviewed 3 August 2026. How we write this.
Most supplements marketed for longevity have mechanistic or animal evidence rather than proof of longer healthy life in humans.
NAD-related products, resveratrol, spermidine and similar compounds can affect pathways of research interest. Pathway activity is not a lifespan outcome.
Apply an evidence ladder
- Human safety data.
- Human biomarker effects.
- Clinical function or disease outcomes.
- Replication and long-term follow-up.
The basics are less exciting but far better supported: do not smoke, remain active, manage risk factors and maintain social connection.
