Yeast beta-glucans may boost flu vaccine effectiveness

Yeast beta-glucans may enhance antibody response to flu vaccine

A new clinical study published in the Journal of Dietary Supplements found that yeast beta-glucan supplementation significantly increased antibody response to the influenza vaccine in adults aged 50 and over. The findings suggest that beta-glucans may support immune health and improve vaccine efficacy.

Participants aged 50 or over took a supplement for two weeks before and four weeks after receiving the flu vaccine. In the beta-glucan group, 96% had seroprotection, a measure of the immune response, compared to 84% in the placebo group. “Overall, the findings suggest that yeast beta-glucan supplementation may elicit a greater change in antibody titer to seasonal influenza vaccination,” wrote researchers from the University of Florida and Lallem…
