How are Nährstoffcheck and longevity related?

The relationship between a nutrient check (Nährstoffcheck) and longevity is promising but not yet firmly established by high-quality evidence. A nutrient check – via blood biomarkers or DNA-based analysis – can identify deficiencies in vitamin D, B12, omega-3 fatty acids, or trace minerals. Such deficiencies are associated with accelerated aging processes, including oxidative stress, inflammation, and epigenetic changes. However, most evidence comes from observational and mechanistic studies; long-term randomized trials directly linking nutrient optimization to extended human lifespan are lacking. Longevity is multifactorial – genetics, lifestyle, environment, and chance play larger roles than individual nutrients. A nutrient check can provide useful guidance, but it is not a guarantee of a long life. The evidence is mixed: partly mechanistic, partly practice-based, without strong human longevity trials.
