Is it ok to put Smile Toothpaste variants in the fridge or freezer? Can they be thawed?

We have not concluded freeze/thaw testing yet. So, at this time, we do not recommend it.

For clarity, we will only test at an elevated temperature. This helps us test for warmer shipping conditions and to get an expedited read on the formula stability. (Once we hear back with the testing results, we’ll be sure to post it here.)

It’s our understanding that there is typically no need to test at refrigerated temperatures since this is usually the most stable. That said, feel free to refrigerate the formula. This will keep it more stable than storing at room temperature.

We hope that helps!
