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

The MyBody-X DNA metabolism analysis, including a 28-day plan and recipe book, is marketed to optimize personal nutrition and health – also in the context of sleep. The test examines SNPs related to nutrient metabolism, such as caffeine, vitamin B12, or folate. Some variants may theoretically affect sleep (e.g., caffeine metabolism via CYP1A2), but effect sizes are small and clinical relevance is unclear. The 28-day plan likely relies on general dietary advice rather than robust sleep-specific data. No randomized controlled trials demonstrate that such a DNA-based plan significantly improves sleep quality. Sleep is influenced by many factors: stress, light exposure, exercise, and sleep hygiene. The analysis may serve as supplementary information but does not replace medical evaluation for sleep disorders. The evidence is predominantly marketing-driven; actual clinical utility is unproven. Beware of exaggerated claims.
