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

The INFINITY DNA-Test, including a 28-day plan and recipe book, is marketed for sleep improvement. However, the scientific evidence for such consumer DNA tests is weak. While certain genetic variants (e.g., in CLOCK, PER, CRY) are associated with chronotype or sleep duration, their effect sizes are small and often not reproducible. The accompanying plan and recipes likely rely on general sleep hygiene and nutrition advice (e.g., melatonin-rich foods), not on truly personalized genomic data. Important caveat: A DNA test cannot replace medical evaluation for sleep disorders. The evidence for clinically actionable, personalized recommendations from such tests is best categorized as 'marketing' or 'unclear'. Safety note: If you have chronic sleep issues, consult a physician rather than relying solely on a direct-to-consumer genetic test.
