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

The DNA metabolism analysis with a 28-day plan and recipe book is primarily designed for metabolic and dietary guidance, not directly for sleep. However, there is an indirect link: the MTNR1B risk allele (melatonin receptor) affects glucose tolerance after late meals. A randomized crossover trial showed that carriers of this allele have worse glucose tolerance after late dinners, which could disrupt sleep quality. The test might therefore offer insights into optimal meal timing that could benefit sleep. However, the overall evidence for the test's usefulness is weak: most SNPs have tiny effect sizes, and the 28-day plan is largely marketing-driven. For sleep issues, proven interventions (sleep hygiene, light management) are far more evidence-based. Caveat: The test is not a medical device and does not replace professional advice. Genetic effects are polygenic and ancestry-dependent.
