What role does DNA Stoffwechselanalyse | inkl. 28-Tage-Plan & Rezeptbuch play in stress?

The DNA metabolism test with a 28-day plan and recipe book claims to help manage stress through personalized nutrition, but the evidence is weak. It analyzes variants in genes like IL-6 (rs1800795), IL-1B (rs1143634), and GPX1 (rs1050450), which are linked to inflammation and oxidative stress – pathways affected by chronic stress. However, single SNPs have small effect sizes, and no RCT shows that a diet tailored to these genes reduces stress more than general healthy eating. The 28-day plan and recipes may promote balanced nutrition, which can support stress resilience, but this benefit is not genotype-specific. Evidence is primarily mechanistic or marketing-based. For stress management, measuring biomarkers like hs-CRP or cortisol is more actionable. Safety note: Do not start high-dose supplements based solely on such DNA tests without medical supervision.
