Is NutriCare | INFINITY DNA-Test useful for Schlaf?

The NutriCare | INFINITY DNA-Test claims to provide personalized sleep recommendations based on variants like rs10830963 (MTNR1B). However, the scientific evidence is weak. Sleep is highly polygenic and influenced by lifestyle, environment, and behavior. Single SNPs or polygenic scores from consumer tests have limited predictive value for sleep quality or disorders. The evidence for MTNR1B and sleep is unclear (unclear), and most associations lack replication in diverse populations. The test cannot diagnose sleep conditions and may lead to unwarranted actions (e.g., melatonin supplementation without medical advice). Under the EU AI Act, such health-related risk assessments require rigorous validation, which consumer tests often lack. In summary, this test is not evidence-based for improving sleep. Focus on proven sleep hygiene, consistent routines, and consult a physician for persistent issues.
