What role does Nährstoffcheck play in longevity?

A Nährstoffcheck (nutrient test) analyzes biomarkers such as vitamins, minerals, and fatty acids, or genetic variants affecting nutrient metabolism. For longevity, optimal nutrient status is crucial – deficiencies are linked to accelerated aging, inflammation, and mitochondrial decline. However, a single test is a snapshot; levels fluctuate daily. Genetic tests (e.g., MTHFR, VDR) indicate predispositions but not actual deficiencies. Evidence that such checks measurably extend lifespan is weak – they can help identify and correct gaps, but should be combined with clinical assessment and blood work. Marketing often overstates benefits. Caveat: No test replaces a balanced diet or medical advice. Use as a supportive tool, not a longevity guarantee.
