Mucin is a glycoprotein component of mucus, which lines and protects the mucus membranes throughout the body, including the respiratory, gastrointestinal, and urogenital tracts. Scientific studies have established that mucins play a crucial role in maintaining the integrity and function of these membranes by providing lubrication, trapping pathogens, and facilitating their removal. Exogenous mucins (administered externally or as supplements) have been studied for their potential to support or restore mucus barriers, especially in conditions where natural mucus production is impaired, such as dry mouth (xerostomia), dry eye, or certain gastrointestinal disorders. For example, mucin-containing artificial saliva and eye drops are used clinically to relieve dryness and protect mucosal surfaces. However, while the use of mucin in topical formulations is well-supported, evidence for oral mucin supplementation directly improving mucus membrane health systemically is limited and less robust. Most benefits are seen with localized application rather than systemic ingestion. There are also traditional uses of animal-derived mucin extracts (e.g., from snails or pigs) in some cultures for respiratory or gastrointestinal health, but these are less well-documented in the scientific literature. In summary, mucin has a scientifically validated role in supporting mucus membranes, particularly through topical and localized use, with moderate evidence supporting its effectiveness in these contexts.
