When Probulin® probiotics leave our NSF® Certified cGMP facility, they often have a long journey to the customer. Probiotic bacteria do not like extreme temperature changes; in fact, it kills them. Our probiotics are packed inside a properly insulated box with ice, where they maintain a consistent, cool temperature throughout the journey.
