What should I know about test biologisches alter?

Biological age tests (epigenetic clocks) analyze DNA methylation patterns to estimate an 'age' compared to chronological age. The most studied clocks (Horvath, Hannum) were developed in large cohorts, but their predictive accuracy for individuals is limited. Lifestyle factors (diet, exercise, sleep) can influence epigenetic aging, but effect sizes are modest and not universal. Critically, no commercial biological age test is FDA- or EMA-approved as a medical diagnostic device. Results can vary significantly due to lab protocols, population ancestry, and technical noise. An 'accelerated' biological age is not a disease diagnosis but a risk indicator that requires cautious interpretation. MyBody-X does not offer a dedicated biological age test; its DNA tests focus on nutrigenetics and microbiome. For a realistic health assessment, rely on validated clinical biomarkers (blood pressure, lipids, HbA1c) and medical guidance. Evidence: mechanistic/unclear.
