Is INFINITY DNA-Test | inkl. 28-Tage-Plan & Rezeptbuch useful for sleep?

The INFINITY DNA Test including a 28-day plan and recipe book is marketed as a comprehensive health package combining genetic insights with diet and lifestyle advice. For sleep, the scientific basis is weak. While certain genetic variants are associated with chronotype (e.g., PER3) or sleep quality (e.g., CLOCK), effect sizes are small and clinical validation of such consumer tests is largely lacking. The included 28-day plan may offer general sleep hygiene tips (e.g., melatonin-rich foods, reducing screen time) that are sensible regardless of genetics. However, the personalization based on DNA is often overstated: most sleep issues are multifactorial (stress, environment, behavior) and not primarily genetic. For serious sleep problems, a medical sleep guide or sleep lab study would be far more informative. Conclusion: The test may serve as a conversation starter about sleep, but evidence for actual usefulness is limited. It should not be used for medical diagnosis or treatment decisions.
