100 calories all from protein (technically 104 because of the 1g of carb), but about as clean as it gets. Flavors are pretty good considering its so calorie efficient. Would recommend *

I trust ON when it comes to ingredients. But the taste wasn't very good. The birthday cake was barely tolerable. Only plus I would give is that it mixed very easy.*
