Intense and prolonged exercise leads to immune suppression, causing upper respiratory tract infections (URTI). A recent randomized, double‑blind, placebo‑controlled pilot study conducted by a&r showed positive effects for a nutritional supplement on the reduction of URTIs in marathon race participants. The aim of the study was to investigate the potential health benefits of a dietary supplement, IQP-AS-119, in reducing the incidence and severity of URTS in marathon runners, providing an indication of the supplement’s efficacy in aiding the body’s immune system under conditions of stress, as modeled by the marathon run.
