Beta-Glucans are known as “biological response modifiers” because of their ability to activate the immune system. Immunologists have discovered that receptors on the surface of innate immune cells called dectin-1 and complement receptor 3 are responsible for binding to beta-glucans, allowing the immune cells to activate more easily. New studies have shown that many pathogens have the ability to suppress immune activation. By utilizing Beta 1,3/1,6 Glucans, the body may be able to overcome the immune suppression activity of these pathogenic agents. Quercitin, ia an amazing antioxidant, . It may alter and benefit the interaction between two key types of immune cells, Th1 and Th2. NOTE: Although derived from baker’s yeast (Saccharomyces Ceravisiae), Beta Glucan is a pure isolate and does not contain enough yeast proteins to typically cause an allergic reaction.
