How long can probiotics stay un-refrigerated before they lose their potency?
There is no way to guarantee the potency of probiotics if they have been without refrigeration at any time. When probiotic products are shipped without refrigeration, they can be exposed to very high temperatures. Since probiotics are living organisms, you can be guaranteed of their potency only if they have been shipped and stored refrigerated. Natren products are refrigerated from manufacturing throughout the entire shipping process. This has always been Natren’s standard when other companies have misrepresented the potency of their probiotic products by claiming they are shelf-stable; they conveniently don’t mention that their products are not stable when exposed to harsh temperatures in the warehouse, shipping and distribution processes. If other companies cannot guarantee potency of each strain through a printed expiry date, how can you trust any of their claims?
