Longevity intelligence
Science shouldn't live behind a paywall — or a PhD.
Vitalopedia translates thousands of peer-reviewed studies on supplements, habits, and biological ageing into clear scores, expert-curated protocols, and personalised stacks anyone can act on today.

Why we built this
The longevity space is flooded with influencer-endorsed supplements, cherry-picked studies, and opaque marketing claims. We found ourselves spending hours cross-referencing PubMed, reading abstracts, and checking whether a product's citation actually said what its label claimed.
Vitalopedia automates that process. Every product is linked to its primary literature, scored against the weight of evidence in the most respected journals, and checked against the public stances of leading researchers — so you can see at a glance whether a supplement is supported by three Cell papers or three blog posts.
We are not selling anything. There are no affiliate links, sponsored rankings, or paid placements. Scores go up or down purely as the evidence does.
How a product score is built
Every score on Vitalopedia traces back to primary literature — no black boxes.
01
Studies are linked and classified
Each product is associated with peer-reviewed studies. Every study is tagged with its recommendation status (supports, mixed, or contradicts use) along with its study design, funding source, publication status, and sample size.
02
Study quality is factored in
Multiple quality signals combine into a single multiplier. Journal prestige (Nature/NEJM = 2×, JAMA/BMJ = 1.5×), study design (meta-analyses = 3×, double-blind RCTs = 1.5×, animal studies = 0.2×), funding source (industry-sponsored = 0.7× penalty), publication status (retracted = 0, preprints = 0.5×), and sample size (< 30 participants = 0.5×) all influence the score.
03
Expert consensus is applied
If a profiled expert publicly recommends or cautions against a product, that sentiment is reflected in the score. The more experts endorse a product, the stronger the signal.
04
A 0–10 score is produced
The weighted study signal and expert adjustments combine into a final score. Scores update automatically as new studies are linked — a product's standing can rise or fall as the science moves.
Three ways to explore the evidence
Products
Browse scored supplements, compounds, and practices. Each page lists every linked study, its journal, and whether it supports or contradicts use — so you can read the evidence yourself, not just a verdict.
Experts
See what leading longevity researchers, physicians, and scientists actually use. Each profile maps their public recommendations to the underlying studies, so you can track the reasoning — not just the conclusion.
Protocols
Curated stacks targeting specific longevity pathways: NAD⁺ metabolism, mitochondrial health, sleep, cognition, and more. Or generate a personalised protocol based on your own goals with our AI protocol builder.
Our principles
Evidence first
If a product lacks studies in reputable journals, that shows in its score. Popularity, price, and branding are irrelevant.
No sponsored content
Rankings are determined entirely by the algorithm. No paid placements, no affiliate relationships, no partnerships that could bias a score.
Transparent methodology
The scoring formula is documented. Every study link is public. You should always be able to trace a score back to its source.
Healthspan over lifespan
Adding years matters less than adding healthy years. Our content focuses on biological ageing mechanisms, not vanity metrics.
