For adults over 50
Evidence-based longevity, after fifty.
The longevity protocols worth considering after fifty — read against the published evidence, graded for how strong that evidence is, with every source shown.
Evidence-based longevity is the practice of choosing which health protocols to follow by the weight of the published research behind each one — not the confidence of whoever is selling it. After fifty, both the stakes and the noise rise: more spent, more claimed, and less appetite for trial and error. Temple Protocol rates longevity protocols against that evidence, grades how strong it is, and shows every source — so the choices you make with your physician rest on what the research supports rather than on enthusiasm.
What is healthspan?
Healthspan is the number of years a person lives in good health — before chronic disease or disability sets in — as distinct from lifespan, the number of years lived in total. It is the measure evidence-based longevity actually serves: more good years, not simply more years.
In the United States that distinction has widened, not narrowed. A 2024 analysis of World Health Organization data in JAMA Network Open found Americans living an average of 12.4 years with disease or disability — the widest healthspan–lifespan gap of the 183 countries studied, up from 10.9 years in 2000. Population figures do not predict any one life; they explain why, after fifty, the question worth asking of a protocol is what the evidence suggests it does for the years lived well.
What a rating gives you
Every protocol we rate carries two readings and nothing you have to take on faith.
Where the evidence comes from.
A provenance reading — whether a claim rests on randomized trials, long-running cohorts, mechanistic work, or little more than testimonial. The origin of a finding is half of what it is worth.
How strong that evidence is.
A strength reading in coarse, unranked bands — deliberately blunt, because the literature rarely supports a finer verdict than it can carry.
The sources, shown.
Every rating links the literature behind it, so you can read the proof yourself rather than take ours. Where the evidence is thin or conflicted, we name it.
Why it reads differently after fifty
The influencer feed is built for the young and the certain — a new compound each week, sold with confidence by people who profit from your belief. After fifty the calculus changes. The money is real, the claims are louder, and the years you would spend testing them are the ones you are trying to protect.
This is written for adults who have taken the body seriously long enough to have tried the noise and tired of it — who would rather have a sourced, conditional reading of a protocol than a confident one. It asks for patience, and returns something quieter than a promise: the sense that what you are doing is considered, not gambled.
How we weigh the evidence
Our reading borrows the standard of evidence-based medicine, not the tempo of the feed. Each rating weighs consistency and replication, effect size, directness, and the independence of the source — the considerations behind established appraisal frameworks such as the GRADE working group and the CEBM levels of evidence. Where the research is strong, we say so plainly; where it is thin or conflicted, we say that too. The full method is on how we rate, and the citation standard on evidence.
Common questions
- What is evidence-based longevity?
- The practice of choosing which health protocols to follow by the weight of the published research behind each one — rather than the confidence of whoever is selling it. Temple Protocol rates longevity protocols against that evidence, grades how strong it is, and links every source.
- What is healthspan?
- Healthspan is the number of years lived in good health, before chronic disease or disability sets in — as distinct from lifespan, the total years lived. A 2024 analysis of WHO data found the US gap between the two to be 12.4 years, the widest of 183 countries studied.
- Is evidence-based longevity only for people over 50?
- No. The evidence standard is the same at any age. It simply matters more after fifty, when there is more spent, more claimed, and less appetite for trial and error.
- Does Temple Protocol tell me which protocols to follow?
- No. We rate how strong the evidence behind a protocol is and show the sources; the decision stays with you and your physician. We rate; we do not prescribe.
- Is this medical advice?
- No. Temple Protocol is editorial. Health language is conditional — “studies suggest,” “evidence indicates” — and every decision belongs with a qualified clinician. Nothing here diagnoses, prescribes, or replaces your doctor.
