Unflavored and unsweetened whey proteins are really gaining popularity. One of the top sellers is the excellent 100% Any Whey Protein from protein superstars Optimum Nutrition. You get a blend of the 3 top whey proteins, whey isolate, whey concentrate, and hydrolyzed whey. And that's about it. Optimum Nutrition does add some lecithin and natural flavor, to help with mixability and to mask the subtle-but-perceptible taste of completely unflavored whey. But the sweeteners and flavors in your Any Whey shake are up to you, so you can change up the taste any time, and on a shake-to-shake basis, too. Once you find a few good sweeteners and flavors, you may never go back to the buying those huge tubs of a single flavor. Try xylitol as a sweetener, then try organic cocoa powder, fresh or frozen fruit, cinnamon or vanilla extract to make your perfect shake. 100% Any Whey Protein is also great in baking recipes, too. Use Any Whey to make high-protein muffins, cookies and breads.
