What role does Leaky Gut Test play in Schlaf?

The role of a leaky gut test in sleep is not well-established by evidence. The test measures markers of intestinal permeability (e.g., zonulin), which have been linked in some mechanistic studies to the gut-brain axis and systemic inflammation—factors that can influence sleep. However, there is no strong human evidence that a consumer leaky gut test can diagnose or guide treatment for sleep disorders. The test is not clinically validated for sleep; it provides only suggestive data that may be confounded by diet, stress, and medication. For sleep issues, validated tools like sleep diaries, actigraphy, or polysomnography are appropriate. The evidence level is 'mechanistic/marketing'—the connection is plausible but not proven. Consumers should be cautious: a leaky gut test alone cannot assess sleep quality or insomnia. Always consult a physician for sleep concerns.
