Marathon Runners Benefit from Beta Glucan Ingredient

June 7, 2012

Research from Biothera says its patented ingredient can reduce symptoms of upper respiratory tract infection.

Research presented at the American College of Sports Medicine’s annual meeting suggests that Wellmune WGP, a patented beta glucan ingredient, can reduce post-exercise sickness in marathon runners.

“It is common for runners to develop upper respiratory tract infections in the days and weeks following completion of a marathon,” says Wellmune WGP developer Biothera (Eagan, MN). “Based on previous physical stress studies with Wellmune WGP that indicated links between specific biomarkers and improved health, researchers believed that marathoners would benefit from enhanced immune function.”

In a study funded by Biothera, academic researchers assigned 182 runners to consume the baker’s yeast beta glucan (in soluble or dispersible form) or placebo (rice flour) for four weeks daily after participating in a marathon. Subjects consuming either form of Wellmune WGP experienced an average 40% reduction in days with symptoms of upper respiratory tract infection-a reduction significantly better than placebo.
