Upper respiratory tract infections (URTI) involve the infection and inflammation of the sinuses, nasal passages, pharynx, and larynx. They include a range of conditions such as influenza, common cold, rhinitis, pharyngitis or laryngitis.

FPP® supplementation for six weeks resulted in higher concentration
of salivary IgA and lysozyme together with a significant increase in phase II enzyme and SOD expression (i.e., the most important antioxidant of the human airways).

With these significant effects, FPP® helps reduce at any age the whole respiratory oxidative stress in the human airways and the incidence and/or severity of upper respiratory tract infections by helping mucosal defences.
