Synopsis

Source of validity: Scientific
Rating (out of 5): 2

"Fiber Blend" typically refers to a combination of soluble and insoluble dietary fibers, often including ingredients like psyllium husk, inulin, flaxseed, and others. The use of fiber blends to support or treat Leaky Gut Syndrome (increased intestinal permeability) is primarily supported by scientific understanding of gut health, though direct evidence specifically targeting "Leaky Gut Syndrome" in humans is limited. Dietary fibers are well-established for their role in promoting overall digestive health, improving stool bulk, and supporting beneficial gut microbiota. There is growing scientific interest in how certain fibers, especially prebiotic fibers like inulin, may enhance gut barrier function by fostering the production of short-chain fatty acids (SCFAs), such as butyrate, which contribute to the health of the intestinal lining.

However, while animal studies and some small human trials suggest that increased fiber intake can improve markers of gut permeability and reduce inflammation, high-quality clinical trials directly measuring the effect of fiber blends on Leaky Gut Syndrome in humans are lacking. The evidence is therefore indirect: fiber’s benefits for general gut health and microbiome support form the basis for its use in this context, rather than robust, specific clinical proof for Leaky Gut Syndrome. In summary, while scientific rationale exists and some preliminary data are promising, conclusive evidence for fiber blends as a treatment for Leaky Gut Syndrome is currently limited.
