What to watch with NutriCare | INFINITY DNA-Test and Schlaf?

When using the NutriCare | INFINITY DNA test in relation to sleep, keep these points in mind: The test may include variants linked to chronotype (e.g., CLOCK, PER genes) and stress response (e.g., COMT, BDNF), but their individual impact on sleep quality is small and often outweighed by lifestyle. There is no strong evidence that personalized sleep recommendations based on these genes improve outcomes. Cortisol levels (as discussed in the cortisol deficiency article) can affect sleep, but DNA testing for cortisol is not clinically validated. Do not rely on the test to diagnose sleep disorders. For persistent sleep issues, consult a healthcare professional. Evidence: human-moderate (GWAS for chronotype, but no RCTs for genotype-based sleep advice).
