MitoGlucan® contains beta-glucan from baker's yeast (Yestimun®) combined with ubiquinol Q10.

Beta-glucans are found in the cell walls of yeast, cereals, fungi and bacteria. They are long-chain glucose molecules strung together, which have different properties depending on the linkage between the glucose building blocks. The beta-glucan contained in MitoGlucan® comes from the baker's yeast Saccharomyces cerevisiae and consists of β-1,3- and β-1,6-linked glucose molecules.
It is produced in Germany and the yeast is cultivated only on malted barley, hops and water before it is subsequently broken down with the yeast's own enzymes and the beta-glucan is purified (Yestimun® from Leiber).

Our body has no enzymes to break down beta-glucans, so they pass more or less unchanged through the gastrointestinal tract and are therefore counted as dietary fiber. Only some species of bacteria in our intestinal flora can use beta-glucans and other dietary fibers as a food source.
