Bio-Grown Food-Cultured Nutrients result from a broth in which live nutritional yeast is cultured with the listed vitamins, minerals, whole soy flour and food concentrates. Our biologically alive process results in nutrients that are remarkably easy to digest and utilize, while simultaneously offering naturally occuring phytonutrients such as soy isoflavones, beta glucans, bioflavonoids, SOD, glutathione, lipoic acid and enzymes.
