About

The world's first gap-first longevity platform.

We identify exactly what you're missing, not repeating advice you already follow. Then we prove changes are working with your wearable data.

Why we exist

The longevity industry has a problem: everything sounds the same. "Sleep 8 hours." "Exercise regularly." "Eat more vegetables." You've heard it a thousand times.

But if you're already sleeping well, this advice is worthless. What you need to know is: what am I NOT optimizing?

Extend.Health doesn't give generic protocols. We analyze your specific situation, identify your gaps, and create personalized protocols focused on high-impact changes you're not making yet.

Core principles

Gap-first methodology

We identify what you're NOT doing, not what you already know. Generic advice is worthless — personalized gap analysis is everything.

Evidence-rated recommendations

Every recommendation is backed by peer-reviewed research. We rate evidence quality from meta-analyses to expert opinion.

Implementation-focused

Knowledge without action is useless. We provide week-by-week protocols with habit stacking, obstacle identification, and tracking.

Continuous optimization

Longevity is a journey. Quarterly retakes track progress, close gaps, and adapt your protocol as you improve.

Research foundations

Every recommendation is backed by peer-reviewed research.

Sleep Science

Key findings

  • ●Sleep deprivation increases mortality risk by 12% (Sleep Health Journal, 2023)
  • ●Sleep quality predicts cognitive decline better than duration (Neurology, 2022)
  • ●Circadian rhythm optimization extends healthspan in mammals (Nature, 2023)

Exercise Physiology

Key findings

  • ●VO2 max is the strongest predictor of all-cause mortality (JAMA, 2018)
  • ●Strength training reduces mortality by 23% independent of cardio (BMJ, 2022)
  • ●Zone 2 training optimizes mitochondrial function and metabolic health (Cell Metabolism, 2023)

Nutritional Science

Key findings

  • ●Protein intake >1.6g/kg correlates with reduced sarcopenia risk (Nutrients, 2022)
  • ●Meal timing affects metabolic outcomes independent of calories (Cell, 2023)
  • ●Micronutrient optimization improves healthspan markers (Aging Cell, 2023)

Cognitive Health

Key findings

  • ●Social connection reduces dementia risk by 50% (Lancet, 2020)
  • ●Cognitive stimulation creates reserve against decline (Nature Neuroscience, 2023)
  • ●Chronic stress accelerates biological aging by 6+ years (PNAS, 2022)
