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

The DNA metabolism analysis with a 28-day plan and recipe book is marketed as personalized nutrition, but its usefulness for fertility is not supported by strong evidence. While certain genetic variants (e.g., MTHFR, VDR) can influence nutrient metabolism—and nutrients like folate, vitamin D, and iron are relevant for fertility—the effect sizes are small and predictive power is limited. The included 28-day plan and recipe book are likely based on general dietary guidelines rather than robust, fertility-specific data. Fertility is multifactorial, involving age, hormonal balance, cycle health, lifestyle, and medical conditions. A DNA test alone cannot address these. The evidence for fertility benefit is best rated as 'marketing'. Caveat: Not diagnostic; consult a healthcare provider for fertility concerns.
