Beta-1,3/1,6-glucan is a polysaccharide isolated from the cell wall of Saccharomyces cerevisiae. The immunity stimulation by Beta-1,3/1,6-glucan consists of increasing the activity of macrophages, which ‘devour’ foreign cells (germs). The increased number of immunity cells in a place where pathogens occur stabilize inflammations and deactivate antigens. Beta-1,3/1,6-glucan enhances the effects of preparations used to treat infectious diseases and cancer, and accelerates the tissue regeneration. ImmunoDol is used during administration of drugs and vaccines, during convalescence, in stressful situations, during reproduction, and decreased immunity. In young dogs in order to form a stable immune system.
