What it is

Beta-glucan is a class of polysaccharides from sources including oats, barley, yeast and fungi. Source and molecular structure matter.

Sources: National Library of Medicine, PubMed

A systematic review of 30 randomised trials of commercial beta-glucan products found mostly small studies and surrogate outcomes. It characterised conclusions as preliminary because study quality and outcome relevance were limited.
