Myths vs facts: NutriCare | INFINITY DNA-Test and Stress

The NutriCare | INFINITY DNA test often claims to analyze genetic variants linked to stress resilience (e.g., COMT, BDNF, FKBP5). However, the scientific basis is weak: most of these SNPs have small effect sizes and were studied in heterogeneous populations. A DNA test cannot reliably predict your current stress level or individual stress susceptibility. Stress is a complex interplay of environment, lifestyle, psychology, and epigenetics – a genetic test alone provides no clinically actionable diagnosis. Current evidence suggests these tests rely on inflated correlations and offer few recommendations that wouldn't be obvious without the test (e.g., sleep, exercise, mindfulness). Be cautious of marketing hype: the evidence is mostly mechanistic or from association studies, not from randomized controlled trials. A physician or psychologist can assess stress far better than a DNA test. If you still choose to test, treat results as curiosity, not a medical guide.
