What happens if I forget to refrigerate KeVita™?

We cannot predict, which is why we clearly label all KeVita™ drinks to be kept refrigerated (our distributors use refrigerated trucks.) If left out for a day or two it seems to be fine. We do know that KeVita's™ delicate flavors taste best when kept refrigerated at all times. Also, the live probiotic content is maintained by continual refrigeration.
