Abstract
Review of human and mechanistic evidence for orally administered yeast-derived beta-glucans.
Key Findings
Human trials of oral yeast beta-glucans report reduced incidence or severity of upper respiratory tract infection symptoms in some populations, but results are inconsistent across preparations.
Conclusions
Immune effects of yeast beta-glucans are plausible but not consistently demonstrated.
Limitations
Heterogeneous preparations and doses; many small industry-funded trials.
Supplements Studied
Human trials of oral yeast beta-glucans report reduced incidence or severity of upper respiratory tract infection symptoms in some populations, but results are inconsistent across preparations.
Outcomes Measured
Human trials of oral yeast beta-glucans report reduced incidence or severity of upper respiratory tract infection symptoms in some populations, but results are inconsistent across preparations.
