I've been looking for a low calorie drink I can drink. I have a hard time drinking regular crystal light because of the artifical sweetners and I need something to replace my series addiction to pop/soda. Well they just came out with the pure fitness which doesn't have any artificial sweetners in it. It has more calories than the reg. stuff...I think regular stuff has 5 calories and this has 30 for 16 oz so it is still low calorie. And best of all it tastes really good. Usually they taste kind of watered down to me but this doesn't I really like it! I tried the strawberry kiwi flavor!
