Is NutriCare | INFINITY DNA-Test useful for sleep?

The NutriCare | INFINITY DNA test from MyBody-X is designed for nutrition-related genetic variants (e.g., lactose intolerance, caffeine metabolism, lipid processing). The available context does not mention any sleep-specific markers such as those for melatonin synthesis, circadian clock genes, or sleep disorders. Therefore, this test is not useful for assessing sleep quality or diagnosing sleep issues. Even if some indirectly relevant SNPs (e.g., in COMT or ADORA2A) were included, they are not listed, and the evidence for actionable sleep insights is absent. The evidence level is 'marketing' – no peer-reviewed studies support the test's utility for sleep. Caveat: genetic predisposition plays a minor role; lifestyle, stress, and environment dominate sleep outcomes. For persistent sleep problems, consult a healthcare professional rather than relying on a consumer DNA test.
