Evidence check: INFINITY DNA-Test | inkl. 28-Tage-Plan & Rezeptbuch in the context of sleep

The INFINITY DNA-Test, including a 28-day plan and recipe book, is a commercial product often marketed with promises of personalized health and sleep optimization. However, the underlying science is weak: most tested SNPs (e.g., in the CLOCK gene) have only small effects on sleep, which are overshadowed by lifestyle, environment, and individual habits. While a 28-day plan or recipe book may promote generally healthy routines, the claim that DNA results justify specific guidance is not supported by robust clinical trials. Consumer DNA tests are not validated for diagnosing or treating sleep disorders. Anyone with genuine sleep issues should consult a physician or sleep specialist rather than rely on a genetic test with a diet plan. The evidence is predominantly marketing-driven, with mechanistic or observational hints but no randomized controlled trials demonstrating sleep benefits.
