How are Stuhlprobe and longevity related?

The relationship between stool sample (Stuhlprobe) and longevity is primarily through gut microbiome analysis. The composition of gut bacteria is linked to aging, inflammation, and metabolic health. Observational studies suggest that a diverse microbiome is associated with healthier aging. However, evidence is mostly observational and mechanistic; no robust clinical trial proves that a stool test directly predicts lifespan. MyBody-X offers microbiome tests that can indicate imbalances, but results are informational, not diagnostic. Individual variation is high, and lifestyle factors like diet, exercise, and genetics are more influential. Marketing claims often overstate benefits. A stool sample can be part of a holistic health assessment, but not a standalone longevity predictor.
