Beta glucan is a complex carbohydrate or biopolymer of glucose, a simple sugar. Beta-1,3D glucan is the sole active ingredient in beta glucan. It is derived from the cell walls of baker's yeast, making it the precise substance for which the actual glucan macrophage receptor has been identified. Beta-1,3D glucan is technically referred to as a polybranched polyglucose - so complex some refer to it as fiber.
Transfer Point's Glucan 300® has been demonstrated to be one of the most potent and efficacious beta-1,3D glucan supplements available. Glucan 300® modulates the immune system to provide support and balance. It is unlike other immune supplements that simply stimulate or change the immune response in unnatural ways.
