How does beta glucan stimulate the immune system? It is proved that beta-glucan can stimulates both innate and acquired immune responses by binding directly to macrophages and other white blood cells (neutrophils and natural killer (NK) cells) and activating them[8, 9](as shown in figure 1).

beta-glucan increases macrophages' ability to destroy invading microbes or infected cells.
