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.

Probulin takes great pride in our products. If for some reason you are not satisfied with your purchase, you may return it for replacement, credit or refund.
