Beta-glucans are a form of natural soluble dietary fiber found in foods, including grains (such as barley, oats, and corn bran) and Mushrooms (such as maitake, reishi, and shiitake). Interestingly, one of the richest concentrated sources of beta-glucans is found in the cell walls of baker's yeast (Saccharomyces Cerevisae). Regardless of the source, however, all beta-glucans are carbohydrates formed by a string of glucose molecules. They are then absorbed into the body through the intestines.
Beta-glucans are also available in various forms as dietary supplements. Manufacturers extract the key compounds from the soluble part of fibrous foods or from baker's yeast, and then remove all fats and Proteins to refine and purify the extract. Packaged in pills and capsules, the beta-glucans are then sold to prevent or treat various ailments.
