Key Advantages

  • DAO
  • Histamine
  • DAO:Histamine Ratio
  • Zonulin
  • LPS (IgA, IgG, and IgM)

Imbalances in Zonulin, Histamine, DAO and LPS are associated with intestinal permeability, often referred to as “leaky gut.” When the gut barrier may be weakened, a person may be more vulnerable to food antigens, toxins, and unfriendly microbes. Intestinal Permeability can degrade the body’s defenses and opens up the system to increased inflammation.

There are many possible causes of damage to the GI lining and subsequent ‘leaky gut’. Common causes of Intestinal Permeability are bacterial overgrowth, food sensitivities including gluten sensitivity, NSAIDs, and alcohol consumption.

Reducing inflammation and healing the GI lining can help restore the GI barrier and normalise Zonulin, DAO, Histamine, and LPS (lipopolysaccharide).
