How are Nährstoffcheck and Langlebigkeit related?

The NährstoffCheck (nutrient test) and Longevity test from MyBody-X are two distinct DNA-based products that address different but complementary aspects of health. The NährstoffCheck analyzes genetic variants related to the utilization of vitamins, minerals, and other nutrients. The Longevity test examines genes associated with aging processes, oxidative stress, and metabolic regulation. Their relationship lies in the fact that optimal nutrient status is considered a foundation for healthy aging. However, both tests rely primarily on GWAS data with small effect sizes. The evidence is therefore best described as marketing-driven or mechanistic. Neither test can diagnose conditions or predict actual lifespan. Lifestyle factors such as diet, exercise, and sleep have a far greater impact on longevity than the tested genetic variants. Using both tests together may provide general orientation, but they cannot replace medical check-ups or blood work.
