Amino acid derivative
Taurine
Compelling animal ageing biology; human longevity claims remain untested.
Evidence before optimism
Which longevity interventions have actually worked in humans?
A practical evidence map for supplements, healthspan interventions and ageing research. Human outcomes are separated from biomarkers, animal lifespan studies and mechanistic promise.
Evidence snapshot
Interesting does not mean established
Each profile gives human outcomes, biomarker evidence, animal lifespan work, mechanism, safety certainty and direct relevance to longevity separate scores.
Performance and muscle
Creatine monohydrate
Useful evidence for strength and training support; longevity benefits would be indirect.
Amino acids and redox biology
GlyNAC
Small human studies are intriguing, but the claims currently outrun the sample sizes.
NAD+ precursor
NMN
Raises NAD-related biomarkers; broad healthspan benefits have not followed reliably.
Vitamin and deficiency correction
Vitamin D
Important when deficient; extra supplementation is not a universal longevity multiplier.
Cardiometabolic
Omega-3 fatty acids
Some cardiovascular effects are real, but formulation, dose and baseline risk matter greatly.
Three useful tools
A site with jobs to do
No infinite scroll of generic wellness copy. The database, trial radar and stack audit each answer a different practical question.

Editorial position
The uncertainty stays on the page
- Human outcomes are not replaced with molecular mechanism when the trial result is disappointing.
- Animal lifespan evidence is labelled as animal lifespan evidence.
- Study doses are recorded descriptively, not converted into personal prescriptions.
- Conflicts of interest and commercial dependence are treated as relevant context.
- Negative and null findings remain visible.
“A molecule can be biochemically fascinating, commercially successful and clinically unproven at the same time.”Editorial principle, Longevity Evidence Lab
