What role does Longevity DNA Test play in Müdigkeit?

The MyBody-X Longevity DNA Test claims to provide insights into biological age and lifespan extension. For fatigue, however, the test offers no robust evidence. The SNPs used have tiny effect sizes and explain only a fraction of variance in aging processes. Fatigue is multifactorial (sleep, nutrition, stress, hormones, infections) and cannot be predicted by a few genetic variants. The test's claims are largely marketing-driven and not supported by clinical studies. Single-SNP analyses, as often used in such tests, are inappropriate for complex traits like fatigue. Instead of a DNA test, individuals should seek medical evaluation (e.g., blood count, thyroid, vitamin deficiencies). The test may serve as a nudge toward a healthier lifestyle but not as a diagnostic or therapeutic tool.
