Evidence-based research, clinical protocols, and expert analysis covering every dimension of human longevity — from epigenetics to metabolic health.
Every article is 2,000+ words, peer-reviewed, and built for people who demand evidence — not hype.
We turn complex research into clear, actionable visuals. Every chart is built from peer-reviewed sources.
Not theory — implementation. Each protocol guide walks you through exact steps, timing, dosing, and how to measure outcomes.
The complete guide to ordering, interpreting, and optimizing your comprehensive longevity blood panel — 38 biomarkers explained.
A 12-week progressive training protocol proven to raise VO2 max — the single most predictive biomarker for longevity.
How to implement TRE correctly — including optimal eating windows, what breaks a fast, and how to track metabolic response.
38 key biomarkers explained in plain language — with optimal ranges, what drives them, and how to move the needle.
The most predictive cardiovascular longevity marker — far superior to standard LDL cholesterol
Detects insulin resistance years before HbA1c — a silent driver of metabolic aging
Chronic low-grade inflammation is central to every major age-related disease
Balancing growth versus repair — the paradox at the heart of longevity research
Every tool on this site is free, requires no account, and is grounded in the same peer-reviewed research as our articles. Start anywhere.
Longevity content on the internet ranges from rigorous to reckless. Here is exactly how we produce ours — and how to hold us to it.
Every claim on this site is grounded in human clinical evidence where it exists. Animal studies and mechanistic data are noted where scientifically relevant, but we never use them as the primary basis for recommendations. When human evidence is absent or conflicting, we say so explicitly — including for popular interventions that haven't earned the evidence their marketing implies.
Every article in our library is researched against peer-reviewed scientific literature, with all factual claims sourced to published studies via numbered citations. When evidence is preliminary, contested, or uncertain, articles say so explicitly. Readers are encouraged to verify claims using the cited references and to consult their healthcare providers.
Every factual claim is cited to a primary source — not another health website, not a press release, not a manufacturer's white paper. We link to peer-reviewed journals and include author, journal, and year so you can verify our interpretation. We actively encourage readers to check our sources and reach different conclusions if the evidence supports it.
Resveratrol is Grade D in our supplement database — despite being one of the most heavily marketed longevity supplements of the past two decades. The Protocol Showdown gives carnivore diet an honest evidence assessment against Mediterranean despite its passionate advocates. We follow the evidence, even when it conflicts with what is popular, profitable, or what our audience might want to hear.
Longevity science moves fast. When major new trials publish, we update our tools, articles, and evidence grades. The Research Radar publishes monthly. The Supplement Evidence Database carries a "last reviewed" date. When we change a grade or recommendation, we note what changed and why — we don't quietly update without acknowledgment.
We do not accept advertising from supplement companies, pharmaceutical manufacturers, or any health product vendor. We have no affiliate relationships. Our evidence grades are not for sale. This site is free because we believe the science of living longer should be accessible to everyone — not gated behind a subscription or shaped by advertiser relationships.
We built IQ Healthspan because the space was dominated by either oversimplified pop-health content or expensive gated information. The science of aging is too important to leave to marketers.
