Is NutriCare | INFINITY DNA-Test useful for longevity?

The NutriCare | INFINITY DNA-Test is marketed as a comprehensive genetic test for nutrition, fitness, and health, often with claims related to longevity. However, the scientific basis for direct lifespan extension is weak. Most such tests analyze SNPs with small effect sizes that collectively have limited predictive value for longevity. Longevity is influenced by complex interactions of genetics, epigenetics, lifestyle, and environment – a single DNA test cannot capture this. Moreover, independent clinical validation studies for the specific markers used in this test are lacking. Results may serve as a motivational tool for healthier habits but not as a reliable prognosis or medical directive. Evidence grade: marketing/unclear. Beware of exaggerated claims; a balanced diet, exercise, and stress management have proven greater impact on healthy aging.
