Since my husband (the Ca pt) hates the taste of Boost and any other prepared Protein drink, (and trust me we have tried everything we can find) I did find that the Can of Boost Powder does not leave the after taste of chalk in any way. So I put that in smoothies, in puddings in anything I dare and he is willing to take that. Means he gets high calorie, Hi Carb,, Hi protein in low volume and it is working so far. Boost Powder , is a large can available on Amazon and in Walmart , I havent seen it anywhere else, Im told it was orginally Carnation Instant Breakfast and has been bought and rebranded as Boost,
