Zonulin Test

The Zonulin Test is designed to measure levels of zonulin, a protein that regulates the tight junctions in your gut lining. Elevated zonulin can be a marker of increased intestinal permeability, often referred to as “leaky gut.

Your gut barrier plays a vital role in protecting you from unwanted substances, such as toxins, bacteria, and undigested food particles, while still allowing essential nutrients to pass through. When this barrier becomes compromised, it may contribute to:

  • Digestive discomfort (bloating, gas, irregular bowel movements)
  • Food sensitivities or intolerances
  • Autoimmune conditions
  • Chronic inflammation
  • Skin issues (such as eczema or acne)

By measuring zonulin, this simple stool test provides insights into the integrity of your gut barrier and whether increased permeability may be affecting your health.

What's included

Zonulin is a protein that regulates small intestinal and gastro-duodenal permeability through its effects on tight junctions.
