EAGAN, Minn.—Wellmune WGP®, a natural carbohydrate for use in food, beverage and dietary supplements from Biothera, reduced upper respiratory tract infections (URTIs) symptoms and other stress-related symptoms, according to a current study published in Agro Food Industry Hi-Tech (2010;21(1)). The randomized, placebo-controlled, double blind design study evaluated the effect of beta-1,3/1,6 glucan derived from bakers yeast (as Wellmune WGP) on symptoms associated with URTIs and psychological well-being. Moderate to highly stressed subjects (45 men, 105 women) ranging in age from 18 to 65, were administered a placebo, 250 mg/d or 500 mg/d of beta-1,3/1,6 glucan during a four-week treatment period. Subjects in both treatment groups reported fewer URTI symptoms; better overall health and increased vigor; and decreased tension, fatigue and confusion based on the profile of mood states assessment.
