Is Stuhlprobe useful for Langlebigkeit?

The usefulness of a stool sample for longevity is currently a nuanced topic. The gut microbiome is linked to inflammation, metabolism, and immune function—all factors that influence aging. However, direct causal evidence for extending lifespan through microbiome analysis is still limited. Many commercial tests offer personalized dietary advice, but their clinical benefit for healthy individuals is often not well-supported. A stool test can help detect dysbiosis or specific pathogens, but interpretation is complex and highly context-dependent. Without medical guidance, there is a risk of overinterpretation or unnecessary interventions. For evidence-based longevity strategies, established biomarkers like HbA1c, blood lipids, or inflammatory markers are currently more reliable. Stool analysis remains a promising research tool but is not yet a standard part of longevity diagnostics.
