INFORMATION:
So for the smoothies its either the yogurt or the sorbet?

From their website:
Non-fat pro-biotic yogurt is made fresh daily at each store and contains active live yogurt cultures including acidophilus. We won’t use sherbet due to its high calorie and sugar content and our premium signature sorbet is reduced sugar through the use of a pre-biotic blend which includes Inulin (from the chicory root).
