Leaky gut, also known as increased intestinal permeability, is an adverse digestive condition in which the gut barrier becomes more permeable, allowing the entry of luminal content (microbes, toxins, antigens, undigested food particles) to leak through the gut wall into the bloodstream. This condition is linked to various health problems, including GI problems, brain disorders, autoimmune diseases, allergies or food sensitivities, etc. (Graziani et al., 2019).
