The Longevity Biological Age Test uses advanced epigenetic analysis to measure how quickly your body is aging at the cellular level. By examining DNA methylation patterns—chemical markers that change with lifestyle, environment, and health—the test provides a highly accurate estimate of your biological age, which may be younger or older than your actual age. It also evaluates your rate of aging, immune system health, and other longevity-related markers. This information helps you understand how your current habits are impacting your long-term health and guides personalized strategies to improve vitality, slow aging, and extend your health span.
