“…Beta-glucan are obtained from diverse sources such as plants, cereals, algae, bacteria, and fungal entities, producing highly divergent biological effects owing to disparity in physicochemical properties; namely, tertiary configuration, solubility, length of polymer, molecular weight, and degree of branching [ 13 , 14 ]. At present, a growing list of beta-glucan preparations has been a subject of human clinical trials [ 15 , 16 ].…”
