A randomized, placebo-controlled, double blind design study was conducted to evaluate the effect of beta-1,3/1,6 glucan derived from bakers yeast, a commercially available dietary supplement, on symptoms associated with upperrespiratory tract infections and psychological well-being. Moderate to highly stressed subjects (45 men, 105 women) ranging in age from 18–65 (mean age: 39 ± 11 years) were administered placebo, 250 mg, or 500 mg beta-1,3/1,6 glucan during a 4 week treatment period. Subjects in both treatment groups (250 mg and 500 mg beta-1,3/1,6 glucan per day) reported fewer upper respiratory tract infection symptoms, better overall health and increased vigour, and decreased tension, fatigue, and confusion based on the profile of mood states assessment.
