VO2 Max Testing
The gold standard measure of how long you'll live
~$250
Immediate
VO2 max testing measures your maximum oxygen consumption during exercise — the single strongest predictor of all-cause mortality and the gold standard for cardiovascular fitness assessment.
Research consistently shows that VO2 max is a better predictor of longevity than smoking status, blood pressure, or cholesterol levels. Moving from the bottom 25% to even average fitness reduces mortality risk by over 50%. This test gives you your exact number and a roadmap to improve it.
What It Measures
Maximum oxygen consumption (VO2 max in mL/kg/min)
Anaerobic threshold and lactate inflection points
Heart rate zones calibrated to YOUR physiology
Respiratory exchange ratio (fat vs. carb burning)
Exercise efficiency and cardiac output estimation
Fitness age vs. chronological age comparison
Why Gabriel Recommends It
VO2 max is the longevity metric that Dr. Peter Attia calls 'the most powerful marker we have.' The difference between low and elite fitness is a 5x difference in mortality risk. Gabriel uses your VO2 max data alongside your biological age and body composition to create a complete longevity picture — and to prescribe the specific exercise protocols (Zone 2, VO2 max intervals) that will move the needle most.
What to Expect
You'll exercise on a treadmill or bike while wearing a mask that measures your oxygen consumption and CO2 output. The test gradually increases in intensity until you reach your maximum effort — typically 10–15 minutes of actual exercise. You'll need athletic clothing and shoes. No eating 2–3 hours before. Results are immediate.
How Gabriel Interprets This
Conventional practitioners read these results through a disease-focused lens — looking for what's broken. Gabriel reads them through a naturopathic lens — looking for what's out of balance and how to restore it. We see optimal ranges, not just "normal" ranges. We connect findings across all your diagnostics to reveal patterns that siloed specialists miss.
