Influence of yeast-derived 1,3/1,6 glucopolysaccharide on circulating cytokines and chemokines with respect to upper respiratory tract infections
This 2012 randomized, double-blind, placebo-controlled trial evaluated the effects of daily supplementation with 250 mg of Wellmune WGP®, a yeast-derived 1,3/1,6 β-glucan, over 90 days in 100 healthy adults during peak upper respiratory tract infection (URTI) season. Participants recorded daily health logs, and URTI symptoms triggered medical assessments and blood
