Active glucan is a complex of two different mushrooms known for containing β-Glucan, a polysaccharide comprised of β-linked d-glucose molecules, known for its immunostimulant activity. Various β-glucans have been extracted from multiple sources such as fungi, baker`s yeast, barley, oats, and seaweed. β-Glucans have been demonstrated to reduce blood lipid levels, including cholesterol and triglyceride. In addition, β-glucans have also been reported to possess various other biologic activities, for example, lowering blood glucose levels, enhancing insulin response, protecting against stress ulcers, and restraining allergic reactions.
