Do the Kefir and Culture Starters need to be kept refrigerated at all times? Why do they say to keep refrigerated on the boxes but are not shipped refrigerated or on ice?

It is best to refrigerate, or ideally freeze the Kefir and Culture Starters to ensure that they last for their full shelf-life at optimal potency. However, they are fine to store unrefrigerated for weeks at a time without considerable loss of potency. Transit times are not nearly long enough to affect the efficacy of the starters.
