The present technology may include a stabilized mass of highly refined cellulose fiber as a prebiotic composition alone or with a probiotic composition. The prebiotic composition may comprise both the prebiotic material blended with and stabilized by highly refined cellulose fiber material. The prebiotic components may be combined with at least 1% by weight of combined probiotic as highly refined cellulose in a blend with the probiotic. The mass may flow as a liquid, may be in a frozen state or may be in a dried powder state or dried solid mass.
