Unhappy with Shipping
Disappointed to purchase a product that is supposed to be kept refrigerated, and see that it was not shipped with an ice pack or some way to keep it cold. Previous orders have been handled better.

Hello, trust our third-party testing that shows our probiotics are FULLY guaranteed through the expiration date, even including short transit times. Icepacks only offer superficial stability and actually draw moisture in to the package which is bad for the dry probiotic powder. We control the water content and oxygen content in every bottle in numerous Quality Control measures, so I can fully assure you after 20+ years of doing this, that your product is fully active! If you don't feel the positive difference in taking our products, we guarantee them with a 100% money-back policy!
