Find Out What Actually Works to Slow Aging & Boost Vitality.
We analyze thousands of peer-reviewed human clinical trials to separate real longevity science from overhyped supplements, marketing noise, and social media fads.
Top Evidence-Ranked Longevity Leaders
Ranked purely by peer-reviewed human clinical evidence, safety margins, and verified biological effect sizes.
High-Intensity Interval Training (such as the Norwegian 4x4 protocol at 90-95% HRmax) maximally expands left ventricular stroke volume, elevates the cardiorespiratory fitness ceiling (VO2 max), upregulates leukocyte telomerase reverse transcriptase (TERT) by 2-3 fold, and targets the single strongest clinical predictor of all-cause mortality reduction.

Progressive resistance exercise (30-60 min/week) is an essential, foundational pillar of human healthspan. It elevates skeletal muscle mass, triggers osteocytic bone mineral accretion, secretes endocrine myokines (IL-15), prevents sarcopenia/dynapenia, and reduces all-cause mortality by 17-40% (compounding to 40% when paired with aerobic exercise).
Low-intensity steady-state endurance training (aerobic base training at blood lactate 1.5-2.0 mmol/L) maximally stimulates mitochondrial biogenesis, enhances fatty acid beta-oxidation, and directly predicts long-term cardiorespiratory fitness (VO2 max), the single most potent non-pharmacological predictor of all-cause mortality reduction.
DunedinPACE (Pace of Aging, Computed from the Epigenome) is a third-generation blood DNA methylation biomarker developed by Belsky, Caspi, and Moffitt from the longitudinal Dunedin Study cohort. Unlike first-generation (Horvath, Hannum) and second-generation (PhenoAge, GrimAge) clocks which measure biological age as a static odometer, DunedinPACE functions as an instantaneous speedometer—quantifying the biological pace of deterioration per chronological year across 19 multi-organ physiological biomarkers. A DunedinPACE score of 1.0 indicates aging at the expected chronological pace, whereas scores below 0.8 indicate a decelerated pace of aging associated with markedly lower morbidity and mortality.

Featured Protocol Stack Audits
Deep Sleep Stack
Optimized nutritional sleep neuro-stack designed to cross the blood-brain barrier, accelerate GABAergic relaxation, induce SCN hypothermia, and extend slow-wave deep sleep.
Metabolic Reset
Fast-acting insulin-sensitizing routine. Clears hepatic glycogen, restores peripheral insulin responsiveness, rescues mitochondrial fatty acid oxidation, and suppresses systemic inflammaging.
The Huberman Morning Routine
The canonical Huberman morning protocol: 10-15 minutes of direct solar photon exposure, cold water immersion hormesis, and delayed caffeine to prevent the afternoon adenosine crash.
Hot Contested Longevity Debates
Opposing viewpoints curated under the Steel-Man standard: voted on by the opposing camp as the highest-signal intellectual representation.
Rapamycin Dosing: Weekly Pulsed Dosing vs. Continuous Low-Dose Inhibition
Should rapamycin for longevity be administered as a single weekly bolus (5-8mg once per week) to maximize peak mTORC1 inhibition while allowing mTORC2 to recover, or does lower continuous micro-dosing provide steadier autophagy?
Metformin: Essential Geroprotector or Blunter of Exercise Adaptations?
Given evidence that metformin attenuates VO2 max and mitochondrial adaptations to aerobic exercise in healthy adults, should non-diabetics who already exercise take metformin for longevity?
NAD+ Augmentation: Nicotinamide Mononucleotide (NMN) vs. Nicotinamide Riboside (NR)
Both NMN and NR effectively raise circulating and tissue NAD+ levels, but intense debate surrounds whether NMN is directly imported via the Slc12a8 transporter or dephosphorylated extracellularly into NR prior to cell entry.
Dietary Protein Intake: Sarcopenia Defense (1.6-2.2g/kg) vs. mTOR Longevity Suppression (0.8g/kg)
Should longevity protocols prescribe high dietary protein to maximize skeletal muscle preservation and prevent frailty, or should protein (specifically leucine and methionine) be restricted to avoid chronic mTORC1 stimulation and accelerated biological aging?
GH / IGF-1 Secretagogues: Tissue Regeneration vs. Oncogenic Proliferation Risk
Growth hormone secretagogues (such as Sermorelin, Ipamorelin, and CJC-1295) restore youthful GH pulsatility and accelerate tissue repair, but elevating systemic IGF-1 may accelerate neoplastic transformation and shorten longevity.
Resveratrol: SIRT1 Longevity Activator or Overhyped PAINS Artifact?
Once heralded as the premier red-wine polyphenol that activates sirtuins and mimics caloric restriction, resveratrol is now intensely contested regarding in vivo bioavailability, off-target fluorescence artifacts, and failure in non-obese human trials.
