Questions people ask about Longevity Test

A longevity test from MyBody-X can measure biomarkers like cortisol, DNA variants (e.g., ACTN3, MC1R), and the gut microbiome. However, interpretative caution is essential. Cortisol levels follow a diurnal rhythm; a single reading is unreliable and requires repeat testing and clinical context. DNA variants for athletic performance or addiction risk (rs1800497) have small effect sizes and are not predictive on their own – lifestyle and environment matter far more. Microbiome tests reveal bacterial diversity and composition, which may influence inflammation and energy metabolism, but links to longevity or performance are correlational, not causal. MyBody-X tests are designed for personal insight, not diagnosis or treatment. Evidence ranges from mechanistic to practice-based, with limited clinical validation. Use results to guide diet, sleep, and stress management, but always consult a healthcare professional for medical decisions.
