EFFECTS OF A DIETARY SUPPLEMENT ON THE INCIDENCE OF ACUTE RESPIRATORY INFECTIONS IN SUSCEPTIBLE ADULTS: A RANDOMIZED CONTROLLED TRIAL.

Introduction: although supplementation of specific micronutrients may improve immunologic factors, few studies about the combination of micronutrients with plant extracts on the occurrence of acute respiratory infections (ARI) have been published.

Objectives: to assess the effect of a nutritional supplement with micronutrients and plant extracts on the incidence of ARI in susceptible adults between January and April, 2012.

Methods: a randomized, double-blind, parallel, placebo- controlled clinical trial was performed.
