CM-Glucan Forte is a derivative of baker’s yeast ß-glucan, a large biologically active polysaccharide that can be isolated from the cell walls. ß-glucans have been called nature’s powerful medicine as they were found to help wounds to heal quickly and to fight infections. Over the years, scientists have gained insights into the working mechanisms of ß-glucans and started to understand their effect on the human immune system. In short, ß-glucans have been shown to strengthen the immune response. An imbalance of the immune system is symptomatic of many skin disorders, among those being atopic dermatitis (AD). The highly pure CM-Glucan Forte developed by Mibelle Biochemistry was studied in terms of its beneficial effects on skin conditions with signs of AD.
