Biological Age Testing
Your DNA methylation clock reveals your true age
$250–$500
3–5 weeks
Epigenetic clock testing analyzes DNA methylation patterns across your genome to calculate your biological age — how old your cells actually are, regardless of your chronological birthday.
Your biological age can be years younger or older than your calendar age, and it's one of the strongest predictors of healthspan, disease risk, and longevity. Unlike genetic testing that shows fixed risk factors, biological age is modifiable — giving you a trackable metric to measure whether your health interventions are actually working.
What It Measures
Biological age via DNA methylation patterns
Pace of aging (how fast you're currently aging)
Immune age and immune system function
Telomere length estimation
Organ-specific aging rates
Response to lifestyle interventions over time
Why Gabriel Recommends It
Biological age is the single most important longevity metric. Two 50-year-olds can have biological ages of 38 and 62 — with radically different disease trajectories. Gabriel uses your biological age as the north star metric: every protocol we recommend should be moving this number in the right direction. Retest every 6–12 months to track real progress.
What to Expect
A simple blood draw or saliva collection kit mailed to your home. The sample is analyzed for DNA methylation patterns at hundreds of thousands of sites across your genome. Results arrive in 3–5 weeks with your biological age, pace of aging, and personalized recommendations. Upload to Gabriel for integration with your full health picture.
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.
