What role does NutriCare | INFINITY DNA-Test play in Schlaf?

The NutriCare | INFINITY DNA-Test by MyBody-X is marketed as a comprehensive genetic test that also provides insights into sleep behavior and quality. However, the provided context contains no scientific evidence or specific genetic variants linked to sleep. The claimed role of this test for sleep is therefore based on marketing, not validated research. In practice, certain gene variants (e.g., in CLOCK, PER3, or ADRB2) can have a small influence on chronotype or sleep duration, but the effects are minor and overshadowed by lifestyle factors such as light exposure, stress, and diet. Such a DNA test cannot replace clinical sleep diagnostics and offers no actionable advice that wouldn't be achievable without testing (e.g., regular bedtimes, melatonin sensitivity). Caution is warranted: results may cause unnecessary worry or false expectations. For evidence-based sleep guidance, medical or sleep specialist evaluations (e.g., polysomnography) are far more reliable. The test remains a lifestyle product with limited utility.
