Good morning!
Ensure does have a clear option that I have seen in stores. What I prefer is Boost Breeze. I was able to order it on Amazon and I like the peach flavor and the berry. It has 250 calories and 9 grams of protein per 8 oz. They look like the juice boxes you buy for kids.
I like the Boost over the Ensure because the Ensure had a funny aftertaste to me.
