How are Leaky Gut Test and sleep related?

The relationship between a Leaky Gut Test and sleep is plausible from a mechanistic perspective but lacks direct clinical validation. Leaky gut tests measure markers of intestinal permeability (e.g., zonulin, lipopolysaccharide-binding protein). Disrupted gut barrier function can promote systemic low-grade inflammation (e.g., via IL-6, CRP), which is known to interfere with sleep regulation through the HPA axis and circadian pathways. Conversely, sleep deprivation itself can increase gut permeability. However, MyBody-X tests are marketed as wellness tools, not diagnostic devices. No published studies specifically link their leaky gut test results to sleep outcomes. The evidence is therefore mechanistic or unclear. Consumers should interpret such tests cautiously and consult a healthcare professional for sleep issues rather than relying solely on home test results.
