What role does Leaky Gut Test play in Langlebigkeit?

The leaky gut test measures intestinal permeability, typically via sugar molecule absorption (lactulose/mannitol). Increased permeability is linked to chronic inflammation, autoimmune conditions, and metabolic disorders—all factors that can accelerate aging. However, no direct human studies show that a positive leaky gut test predicts longevity or that targeted interventions extend lifespan. The evidence is mostly mechanistic, based on animal models or observational associations. Commercial tests often lack standardization, and results are difficult to interpret. While gut health is relevant to longevity research, the test alone does not provide a solid basis for anti-aging strategies. Caveat: Self-diagnosis without medical guidance may lead to unnecessary dietary restrictions or supplements.
