Beta Glucan, a natural component of yeast, triggers an immune response in the body creating a system of defense against viral, bacterial, fungal, parasitic or potentially cancerous invaders. It also has potent antioxidant free-radical scavenging capabilities, stimulates the production of immune cells, lowers cholesterol, regulates glucose levels, and enhances the phagocytosis activity of macrophage white blood cells to fight invaders or clean up toxins and debris in the body.
