Microbiome Labs Mega Mucosa is the first supplement specifically designed to restore and support the intestinal mucosal barrier — the mucus layer lining the gut that serves as the first line of defense between intestinal contents and the underlying epithelium. Mucosal layer thinning, caused by modern diets, antibiotics, stress, and dysbiosis, is a primary driver of leaky gut and systemic inflammation. 5.5oz powder.The formula targets the mucosal barrier through multiple complementary mechanisms: Immunoglobulins (from serum-derived bovine immunoglobulin/IgG concentrate) directly bind and neutralize inflammatory antigens, toxins, and pathogenic bacteria in the intestinal lumen — reducing the inflammatory load the mucosa must manage. L-Proline and L-Serine are the primary amino acids required for mucin synthesis — the glycoprotein that forms the viscous mucus layer. L-Threonine is the most abundant amino acid in mucin and is directly rate-limiting for mucosal layer thickness. The combination of immunoglobulin support + mucin amino acid precursors addresses both the immunological and structural components of mucosal barrier function. Microbiome Labs clinical data shows meaningful improvement in intestinal permeability markers and gut comfort. Microbiome Labs is a science-first probiotic and gut health supplement company founded by Dr. Kiran Krishnan, a research microbiologist, built around spore-based probiotic technology and clinical research on the human gut microbiome.
