Supplements with real longevity evidence
The longevity supplement space has a high ratio of hope to evidence. These are the compounds with either solid preclinical data plus emerging human trials, or strong biomarker evidence (inflammation, mitochondrial function) that predicts long-term outcomes.
The short list
Essential fats (EPA/DHA) that support cardiovascular and brain health.
A compound essential for cellular energy production.
A NAD+ precursor studied for cellular energy and longevity.
A NAD+ precursor with human clinical research.
A polyphenol from grapes studied for longevity and cardiovascular health.
A polyamine that may promote autophagy and cellular renewal.
A fat-soluble vitamin that directs calcium to bones rather than arteries.
A fat-soluble vitamin essential for bone health and immune function.
Frequently asked
- Is NMN better than NR?
- Both raise NAD+. NR has more human trial data at this point, though NMN has caught up recently. Bioavailability and dose matter more than which one you pick.
- Do longevity supplements actually extend lifespan in humans?
- No supplement has been proven to extend human lifespan. What's reasonable to claim is healthspan signals: better inflammation markers, mitochondrial function, cardiovascular biomarkers. Expect modest, slow effects.
- What's the most important longevity supplement?
- If you're picking one: omega-3 (EPA/DHA). Decades of data, broad cardiovascular + cognitive + inflammatory benefits, very low risk. NAD boosters are higher-variance bets on newer science.
