Truage Test

Created with science from Harvard, Yale, and Duke, the TruAge test measures +75 key biomarkers for longevity to give you the most precise, accurate, and actionable insights about your aging. Drawing from the largest private DNA methylation database in the world, a TruAge report will tell you: biological age, speed of aging, and organ-specific aging. TruAge tells you how fast your 11 key organ systems are aging, including your heart, brain, liver, and lungs and measures hundreds of thousands of CpG sites on your DNA to measure your exact aging speed and give you personalized insights to slow it down. 90% of aging is determined by epigenetics – our lifestyle, diet, and exercise choices. TruAge measures your epigenetics to give you custom insights about what works for your body’s cellular health and what can be improved.

What is the TruAge Test?
TruAge is an advanced epigenetic test that measures how your body is aging at the cellular level. By analyzing DNA methylation markers, it reveals your biological age, pace of aging, and how key organ systems such as your heart, brain, and liver are performing. The result is a personalized, data-driven report with insights to help you slow aging, optimize health, and improve long-term outcomes.
What to Expect
Here’s what to expect when completing your TruAge test—from preparation to next steps.
• Before Your Test: You’ll receive an at-home kit with step-by-step instructions for collecting a small finger-prick blood sample. For best results, avoid alcohol and high-fat meals for 8 hours beforehand and stay well hydrated.
• Collect & Return Your Sample: Use the included materials to collect your sample and return it using the prepaid mailer. The process is quick, simple, and designed for convenience.
• Review & Apply Your Results: Your results will be uploaded to a secure digital dashboard within a few weeks. You’ll receive a detailed report showing your biological age, pace of aging, and organ-specific insights—along with personalized recommendations to help you take action.
What Can This Support?
• Biological Age & Pace of Aging: Understand how quickly your body is aging at the cellular level—and how it compares to your chronological age.
• Organ System Health: Track how key systems like your heart, brain, liver, and lungs are aging to guide targeted interventions.
• Longevity & Prevention Planning: Use aging insights to inform long-term health strategies, lifestyle changes, and supplement protocols.
• Epigenetic Optimization: Identify how lifestyle, nutrition, and environment are impacting gene expression—and where changes can slow aging.
• Baseline for Advanced Therapies: Establish a data-driven starting point to track progress from peptides, hormone optimization, or regenerative treatments.
