Our probiotic provides powerful dosing and offers increased therapeutic diversity with 12 strains to rapidly replenish beneficial bacteria in the gastrointestinal system. Just by inhabiting the human gut, probiotics encourage bowel motility, balanced and natural immune function. These 12 strains were carefully researched and chosen for therapeutic benefit, resistance to digestion, adherence to intestinal cells, and stability. Unlike many probiotic supplements, BioMaintenance™ Shelf Stable Probiotic does not require refrigeration to maintain its potency.
