What to watch with Leaky Gut Test and Sport?

When combining a leaky gut test with sports, caution is warranted. Most commercial tests (e.g., 'gut health' panels) lack validated biomarkers for intestinal permeability and are often marketing tools with no clinical utility. Exercise can transiently increase gut permeability due to reduced blood flow and heat stress, but a single test cannot reliably guide your training or nutrition. Evidence for genetic or microbiome-based leaky gut tests is weak. Instead, focus on proven strategies: stay hydrated, time carbohydrate intake around intense sessions, avoid NSAIDs, and prioritize recovery. If you still take a test, interpret results conservatively and consult a sports medicine professional or dietitian.
