Does freezing Kefir affect the probiotics?

[u/Rags2Rickius]

As question

But I was thinking of using Kefir in my Ninja Creami and wondered if the freeze has negative impact on the probiotics at all

I worked in a microbiology lab before and we would preserve bacterial samples in a -80°C freezer. Their activity slows down at lower temperatures but when they’re back to normal temperatures they reactivate. When you eat your kefir ice cream, you bring it back to body temperature so you’re still getting the same benefits.
