Science of Throat Coating

Low humidity in flights dries out mucosal surfaces, weakening the body’s first line of immune defense.

• Frequent sipping of flavorful, slightly acidic drinks can stimulate saliva, hydrate mucus membranes, and flush pathogens toward the stomach.

• Saliva and mucus act as physical barriers to infection.

• Ingredients like citric acid, ginger, and coconut water powder support this mechanism.

• Some research suggests that acidic or astringent flavors enhance salivation, which helps coat the throat and may trap or neutralize airborne pathogens.

• Maintaining saliva flow and mucosal integrity is linked to reduced transmission of upper respiratory viruses. This “throat coating” effect helps form a transient protective layer against environmental pathogens.

• Prebiotic compounds and polyphenols (e.g. from elderberry or turmeric) may also influence oral and throat microbiota in a way that benefits immune readiness.

• Some botanical compounds may also increase mucin secretion—glycoproteins that form the structure of mucus and help trap and neutralize viruses before they enter cells.

• Moist airways are also associated with better mucociliary clearance, which helps eliminate inhaled particles and potential pathogens.
