What to watch with Leaky Gut Test and Haut?

When combining a Leaky Gut Test with skin issues („Haut“), caution is warranted. The concept of 'leaky gut' (increased intestinal permeability) is scientifically debated – there is no standardized, clinically validated test for it. MyBody-X and similar providers often rely on markers like zonulin or lipopolysaccharides, but their ability to diagnose a 'leaky' gut barrier is insufficiently proven. The gut-skin axis is real: studies link the gut microbiome to skin conditions such as acne, rosacea, and eczema. However, the evidence is mostly mechanistic and correlational, not causal. A single test cannot derive personalized diet or treatment. The risk lies in overpromising: expensive supplements or restrictive diets are often recommended without clinical benefit. Instead, individuals should focus on proven measures: a high-fiber diet, adequate sleep, stress reduction, and consulting a dermatologist for skin issues. Test results should be considered exploratory, not diagnostic. Evidence grade: mixed (gut-skin axis mechanistically supported, test claims marketing).
